网络图

注意：在此拓扑中，BR1-VE-1和BR3-VE-1的GOLD TLOC是共同的。在实际场景中，站点可以具有相同或不同的TLOC。

配置

BR1-VE-1具有SD-WAN重叠/底层基本配置和默认路由。此外，本地组播复制器和PIM已配置在Ge0/0接口上，命令multicast-replicator local将VE路由器配置为组播复制器。

vpn 10
 router
  multicast-replicator local
  pim
   auto-rp
   interface ge0/0
   exit
 !
 interface ge0/0
  ip address 192.168.1.1/24
  no shutdown

BR3-VE-1具有SD-WAN重叠/底层基本配置和默认路由。此外，IGMP和PIM在Ge0/0接口上配置。

vpn 10
 router
  pim
   auto-rp
   interface ge0/0
   exit
  !
  igmp
   interface ge0/0
   exit
 !
 interface ge0/0
  ip address 192.168.3.1/24
  no shutdown

RP路由器还具有基本底层配置和默认路由。

注意：必须使用非viptela设备作为RP。在本示例中，运行Cisco IOS® XE软^件的CSR已用于此目的。

ip multicast-routing distributed
!
interface Loopback0
 ip address 192.168.101.1 255.255.255.255
 ip pim sparse-mode
!
!
interface GigabitEthernet2
 ip address 192.168.1.3 255.255.255.0
 ip pim sparse-mode
!
!
!
ip pim send-rp-announce Loopback0 scope 20
ip pim send-rp-discovery Loopback0 scope 20

使用自动RP时，会发生以下事件：

RP映射代理侦听公认组地址CISCO-RP-ANNOUNCE(224.0.1.39)，候选RP通告将发送到该地址。当您使用Auto-RP分发组到RP的映射时，ip pim send-rp-announce 命令会使路由器向公认组CISCO-RP-ANNOUNCE(224.0.1.39)发送自动RP通告消息。
RP映射代理将自动RP发现消息中的组到RP映射发送到公认组CISCO-RP-DISCOVERY(224.0.1.40)。 TTL值限制消息可以跳数。
PIM路由器会侦听此组，并使用从发现消息中了解的RP。

源路由器是运行Cisco IOS® -XE软^件的CSR，该软件还具有基本的底层配置和默认路由。通过对组播地址执行ping命令生成流量。

ip multicast-routing distributed
!
interface GigabitEthernet5
 ip address 192.168.100.2 255.255.255.0
 ip pim sparse-mode

接收方是运行Cisco IOS® ^-XE软件的CSR，并已通过ip igmp join-group命令配置为IGMP接收方。它还具有默认路由和基本底层配置。

ip multicast-routing distributed
!
interface GigabitEthernet2
 ip address 192.168.3.2 255.255.255.0
 ip igmp join-group 239.1.2.3

验证

您可以使用本节来确认您的配置是否正常工作。

步骤1.接收方向RP发送IGMP加入消息。从接收方输出debug ip igmp 239.1.2.3。

Oct  9 12:29:12.707: IGMP(0): v2 querier for GigabitEthernet2 is this system.
Oct  9 12:29:12.708: IGMP(0): Send v2 init  Query on GigabitEthernet2
Oct  9 12:29:12.708: IGMP(0): Set report delay time to 0.9 seconds for 239.1.2.3 on GigabitEthernet2
Oct  9 12:29:13.669: IGMP(0): Send v2 Report for 239.1.2.3 on GigabitEthernet2
Oct  9 12:29:13.669: IGMP(0): Received v2 Report on GigabitEthernet2 from 192.168.3.2 for 239.1.2.3  <<<<<<<<<<<
Oct  9 12:29:13.670: IGMP(0): Received Group record for group 239.1.2.3, mode 2 from 192.168.3.2 for 0 sources

Oct  9 12:29:17.377: IGMP(0): Received v2 Query on GigabitEthernet2 from 192.168.3.1

步骤2. BR3-VE-1，充当LHR。它接收IGMP加入消息，将此信息发送到RP。这些IGMP加入消息作为OMP更新中组播路由的一部分传输。

BR3-VE-1# show igmp groups 

                       V1                                                                            
     IF                MEMBERS                                           V1                          
VPN  NAME   GROUP      PRESENT  STATE            UPTIME      EXPIRES     EXPIRES  EVENT

步骤3. vSmart通过OMP接收(*,G)条目，并将此信息转发给复制器。

vsmart# show omp multicast-routes
Code:
C -> chosen
I -> installed
Red -> redistributed
Rej -> rejected
L -> looped
R -> resolved
S -> stale
Ext -> extranet
Stg -> staged
Inv -> invalid


ADDRESS SOURCE
FAMILY   TYPE   VPN  ORIGINATOR  DESTINATION    GROUP   SOURCE   FROM PEER     RP          STATUS
-----------------------------------------------------------------------------------------------------
ipv4    (*,G)   10   10.33.33.3   10.11.11.1  239.1.2.3 0.0.0.0  10.33.33.3 192.168.101.1  C,R

步骤4.在此拓扑中，BR1-VE-1充当复制器。BR1-VE-1将此信息转发到RP。

BR1-VE-1# show omp multicast-routes
Code:
C -> chosen
I -> installed
Red -> redistributed
Rej -> rejected
L -> looped
R -> resolved
S -> stale
Ext -> extranet
Stg -> staged
Inv -> invalid


ADDRESS SOURCE FROM
FAMILY  TYPE  VPN  ORIGINATOR  DESTINATION   GROUP     SOURCE      PEER      RP         STATUS
--------------------------------------------------------------------------------------------------
ipv4    (*,G) 10   10.33.33.3   10.11.11.1  239.1.2.3  0.0.0.0   10.1.1.2 192.168.101.1   C,I,R

步骤5. RP现在已创建(*,G)条目。

FHR-RP#show ip mroute 
IP Multicast Routing Table
Flags: D - Dense, S - Sparse, B - Bidir Group, s - SSM Group, C - Connected,
       L - Local, P - Pruned, R - RP-bit set, F - Register flag,
       T - SPT-bit set, J - Join SPT, M - MSDP created entry, E - Extranet,
       X - Proxy Join Timer Running, A - Candidate for MSDP Advertisement,
       U - URD, I - Received Source Specific Host Report, 
       Z - Multicast Tunnel, z - MDT-data group sender, 
       Y - Joined MDT-data group, y - Sending to MDT-data group, 
       G - Received BGP C-Mroute, g - Sent BGP C-Mroute, 
       N - Received BGP Shared-Tree Prune, n - BGP C-Mroute suppressed, 
       Q - Received BGP S-A Route, q - Sent BGP S-A Route, 
       V - RD & Vector, v - Vector, p - PIM Joins on route, 
       x - VxLAN group
Outgoing interface flags: H - Hardware switched, A - Assert winner, p - PIM Join
 Timers: Uptime/Expires
 Interface state: Interface, Next-Hop or VCD, State/Mode

(*, 239.1.2.3), 1d12h/00:02:51, RP 192.168.101.1, flags: S
  Incoming interface: Null, RPF nbr 0.0.0.0
  Outgoing interface list:
    GigabitEthernet2, Forward/Sparse, 1d12h/00:02:51

步骤6.现在，轮到源设备向RP注册。在本示例中，组播流量是使用ping命令生成的，其中组播地址作为目标。

Source#ping 239.1.2.3 repeat 10
Type escape sequence to abort.
Sending 10, 100-byte ICMP Echos to 239.1.2.3, timeout is 2 seconds:

<SNIP>

源设备向RP发送注册消息。

FHR-RP#show ip mroute 
IP Multicast Routing Table
Flags: D - Dense, S - Sparse, B - Bidir Group, s - SSM Group, C - Connected,
       L - Local, P - Pruned, R - RP-bit set, F - Register flag,
       T - SPT-bit set, J - Join SPT, M - MSDP created entry, E - Extranet,
       X - Proxy Join Timer Running, A - Candidate for MSDP Advertisement,
       U - URD, I - Received Source Specific Host Report, 
       Z - Multicast Tunnel, z - MDT-data group sender, 
       Y - Joined MDT-data group, y - Sending to MDT-data group, 
       G - Received BGP C-Mroute, g - Sent BGP C-Mroute, 
       N - Received BGP Shared-Tree Prune, n - BGP C-Mroute suppressed, 
       Q - Received BGP S-A Route, q - Sent BGP S-A Route, 
       V - RD & Vector, v - Vector, p - PIM Joins on route, 
       x - VxLAN group
Outgoing interface flags: H - Hardware switched, A - Assert winner, p - PIM Join
 Timers: Uptime/Expires
 Interface state: Interface, Next-Hop or VCD, State/Mode

(*, 239.1.2.3), 00:00:12/00:03:27, RP 192.168.101.1, flags: S
  Incoming interface: Null, RPF nbr 0.0.0.0
  Outgoing interface list:
    GigabitEthernet2, Forward/Sparse, 00:00:02/00:03:27

(192.168.100.2, 239.1.2.3), 00:00:12/00:02:47, flags: T
  Incoming interface: GigabitEthernet4, RPF nbr 192.168.100.2
  Outgoing interface list:
    GigabitEthernet2, Forward/Sparse, 00:00:02/00:03:29

<SNIP>

步骤7. BR1-VE-1将PIM(S， G)加入消息转发到vSmart。与IGMP加入一样，PIM(S， G)加入消息作为组播路由器的一部分在OMP更新中传输。vSmart现在在MRIB中创建(S， G)条目。(S， G)信息随后通过OMP转发到复制器和LHR。

注意：在真实场景中，复制器可以位于同一站点或不同站点，具体取决于您的设计首选项。

vsmart# show omp multicast-routes

Red -> redistributed
Rej -> rejected
L -> looped
R -> resolved
S -> stale
Ext -> extranet
Stg -> staged
Inv -> invalid

       (S,G)  10   10.33.33.3  10.11.11.1  239.1.2.3   192.168.100.2 10.33.33.3      -           C,R

BR1-VE-1# show omp multicast-routes

        (S,G)  10    10.33.33.3  10.11.11.1   239.1.2.3  192.168.100.2   10.1.1.2      -          C,I,R

步骤8.最后一跳路由器现在有(S， G)条目。LHR现在向源发送(S， G)连接。

注意：在输出中，您可以看到(*, G)条目和(S， G)条目发起方显示为10.33.33.3，组的目标为10.11.11.1。这是因为LHR BR3-VE-1负责创建(*, G)条目以及(S， G)加入以构建组播控制平面。

BR3-VE-1# show omp multicast-routes
Code:
C -> chosen
I -> installed
Red -> redistributed
Rej -> rejected
L -> looped
R -> resolved
S -> stale
Ext -> extranet
Stg -> staged
Inv -> invalid


ADDRESS SOURCE FROM
FAMILY TYPE   VPN  ORIGINATOR   DESTINATION   GROUP     SOURCE        PEER     RP           STATUS
---------------------------------------------------------------------------------------------------------
ipv4   (*,G)  10   10.33.33.3   10.11.11.1   239.1.2.3 0.0.0.0       0.0.0.0 192.168.101.1  C,Red,R    
       (S,G)  10   10.33.33.3   10.11.11.1   239.1.2.3 192.168.100.2 0.0.0.0     -          C,Red,R

数据平面验证：

理想流量必须是（从、到）：

FHR-RP的来源
FHR-RP到VE
VE到复制器
复制器到LHR
LHR到接收方

注意：本文档不介绍PIM RPT和SPT切换的详细信息。

在本例中，流量如下：

从源到FHR-RP
FHR-RP到BR1-VE-1
BR1-VE-1到BR3-VE-1（通过IPSec数据平面隧道）
BR3-VE-1到接收器

注意：组播流量在BR1-VE-1和BR3-VE-1之间通过数据平面IPsec隧道传输。vSmart控制器从不参与实际流量转发。

在此拓扑中，BR1-VE-1配置为复制器并靠近源。复制器位于与源不同的站点时，可能会出现这种情况。无论如何，确保复制程序驻留的特定站点和站点之间的数据平面隧道都处于工作状态。

故障排除

本部分提供了可用于对配置进行故障排除的信息。

1.验证(*、G)和(S、G)是否存在于RP上。

2.确保您有数据平面隧道，并且BFD会话在VE和站点之间启用，在站点中，复制程序在show bfd sessions命令的帮助下配置。

3.检查BR3-VE-1是否了解BR1-VE-1上的复制程序。

BR3-VE-1# show multicast replicator 

     REPLICATOR  REPLICATOR  LOAD     
VPN  ADDRESS     STATUS      PERCENT  
--------------------------------------
10   10.11.11.1  UP          -

4.确保已与BR3-VE-1建立组播隧道。

BR3-VE-1# show multicast tunnel    

     TUNNEL     TUNNEL              
VPN  ADDRESS    STATUS  REPLICATOR  
------------------------------------
10   10.11.11.1   UP      yes

5.确保组到RP的映射已分发且正确。

BR3-VE-1#show pim rp-mapping

VPN  TYPE     GROUP        RP ADDRESS     
------------------------------------------
10   Auto-RP  224.0.0.0/4  192.168.101.1

6.确保组播路由(*、G)和(S、G)正确传播到vEdge、Replicator路由器和vSmart。使用show multicast topology和show omp multicast-routes命令。

7.检查LHR上的RPF表。

BR3-VE-1#  show multicast rpf | tab

                                                          RPF                             RPF     
                    RPF       NEXTHOP         RPF NBR     IF                RPF TUNNEL    TUNNEL  
VPN  RPF ADDRESS    STATUS    COUNT    INDEX  ADDR        NAME  RPF TUNNEL  COLOR         ENCAP   
--------------------------------------------------------------------------------------------------
10   192.168.101.1  resolved  2        0      10.11.11.1  -     10.11.11.1  biz-internet  ipsec   
                                       1      10.11.11.1  -     10.11.11.1  gold          ipsec   
10   192.168.100.2  resolved  2        0      10.11.11.1  -     10.11.11.1  biz-internet  ipsec   
                                       1      10.11.11.1  -     10.11.11.1  gold          ipsec

8.检查LHR是否通过show ip mfib summary命令获取了有关自动RP和数据组播组的所有必需信息。

9.检查LHR上的show ip mfib oil命令输出是否包含指向接收方路由器的出口接口。

10.使用show ip mfib stats命令检查流量是否流动。

其他有用的debug命令：

debug pim auto-rp level high — 启用auto-rp调试。
debug pim events level high vpn <vpn number> — 启用PIM事件调试。
debug ftm mcast — 启用组播编程调试。

结论

这些场景已在此拓扑中成功测试。

组播源直接连接到同一站点的RP，接收方位于远程站点（测试场景）。
组播接收器直接连接到同一站点的RP，而源设备位于远程站点。
组播源直接连接到VE，而接收方和RP位于远程站点。
