簡介

本檔案介紹如何驗證SD-Access (SDA)光纖中的原生多點傳送。

必要條件

需求

思科建議您瞭解以下主題：

網際網路通訊協定(IP)轉送
定位器ID/分隔通訊協定(LISP)
通訊協定無關多點傳送(PIM)稀疏模式

採用元件

Cisco IOS® XE 17.10.1上的C9000v
Cisco Catalyst中心版本2.3.5.3

本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路運作中，請確保您瞭解任何指令可能造成的影響。

本文件也適用於以下硬體和軟體版本：

Cisco IOS® XE 16.12及更高版本

背景資訊

SDA本地組播是一種重疊組播，用於在交換矩陣裝置之間傳送組播流量，將組播流量封裝到另一個組播組中。本地組播可以在同一個VLAN或不同VLAN中的源和接收器之間路由組播流量（可以路由同一個VLAN組播）。同一交換矩陣邊緣(FE)上的源和接收之間的組播流量不使用重疊組播（VXLAN封裝）進行轉發，而是由FE進行本地路由。本機多點傳送無法路由符合224.0.0.0/24或Time To Live (TTL) =1的群組多點傳送流量，這些流量是透過第2層(L2)泛洪處理。原生多點傳送可以設定為轉送任何來源多點傳送(ASM)、來源特定多點傳送(SSM)或兩者的組合。本地組播依賴於底層組播。

附註：平台 (fed) 命令可能有所不同。命令可以是「show platform fed <active|standby>」或「show platform fed switch <active|standby>」「」。如果示例中註明的語法未解析出，請嘗試該變體。

拓撲

Network Topology 網路拓撲

在此拓撲中：

遠端定位器ID (RLOC) 10.47.1.10和10.47.1.10配置在任意邊界處，還用作任播集合點(RP)，在虛擬網路(VN)或虛擬路由和轉發(VRF)中的兩者之間使用組播源發現協定(MSDP)。
10.47.1.12和10.47.1.3是FE節點
10.47.7.4是組播接收器
10.47.7.3是組播源
239.0.0.5是組播組目標地址(GDA)

組態

假設Cisco Catalyst Center用於使用以下設定調配SDA交換矩陣：

複製模式實施是本地組播
多點傳送模式是任何來源多點傳送(ASM)
任播交匯點(RP)與組播源發現協定(MSDP)配置在任意位置邊界上
底層組播要麼是手動配置的，要麼是作為初始LAN自動化的一部分配置的，本地組播依靠底層組播正常運行。

控制平面驗證

本節將驗證通訊協定無關多點傳送(PIM)，首先驗證第一躍點路由器(FHR)上建立的(S，G)

FHR (S，G)建立

組播源10.47.7.3將UDP組播資料包傳送到239.0.0.5。驗證IP裝置跟蹤(IPDT)、思科快速轉發(CEF)和反向路徑轉發(RPF)是否正確指向組播源。此外，確保任播網關SVI是此網段的PIM指定路由器(DR)。

使用命令「show device-tracking database address <ip address>」確儲存在有效的IPDT條目

Edge-2#show device-tracking database address 10.47.7.3

使用命令「show ip cef vrf <VN Name> <ip address>」並確保組播源已直接連線

Edge-2#show ip cef vrf blue_vn 10.47.7.3
10.47.7.3/32
nexthop 10.47.7.3 Vlan1025

然後，使用命令「show ip rpf vrf <VN> <ip address>」確保RPF介面是源所處的VLAN，而不是LISP。

Edge-1#show ip rpf vrf blue_vn 10.47.7.3
RPF information for (10.47.7.2)
RPF interface: Vlan1025

RPF type: unicast (lisp)
Doing distance-preferred lookups across tables
Multicast Multipath enabled.
RPF topology: ipv4 multicast base, originated from ipv4 unicast base

使用命令「show ip pim vrf <VN name> interface vlan <vlan> detail | include DR|enabled」以驗證FE節點是網段的PIM DR還是FHR。

Edge-2#show ip pim vrf blue_vn interface vlan 1025 detail | include DR|enabled
PIM: enabled
PIM DR: 10.47.7.1 (this system)
PIM State-Refresh processing: enabled
PIM Non-DR-Join: FALSE

使用命令「show ip mroute vrf <VN name> <multicast group address>」驗證(S，G)建立。(S，G)將具有空傳出介面清單(OIL)，因為還沒有相關的接收方或PIM路由器加入FHR。

Edge-2#show ip mroute vrf blue_vn 239.0.0.5

FHR (S，G)註冊

FHR使用配置為「registered-source」PIM註冊消息的介面將單播源註冊到任播RP。

LHR IGMP成員報告

組播接收方傳送IGMP成員報告/加入以表示接收組播流量的興趣，該流量在最後一跳路由器(LHR)上建立IGMP監聽和IGMP組條目。使用命令「show ip igmp snooping groups vlan <vlan id> <group destination address>」和「show ip igmp vrf <VN Name> groups <group>」。

Edge-1#show ip igmp snooping groups vlan 1025 239.0.0.5

接下來，請確保LHR確實是此分段的PIM DR，請使用命令「show ip pim vrf <VN name> interface vlan <vlan> detail | 包含DR|enabled」

Edge-1#show ip pim vrf blue_vn interface vlan 1025 detail | include DR|enabled

Border-1從MSDP SA快取建立(S，G)

FHR恰好將組播源註冊到Border-2。Border-2透過MSDP將組播源通告給Border-1。您可以使用命令show ip msdp vrf <VN Name> summary檢視MSDP狀態。

資料層面驗證（與平台無關）

可能有多種問題會阻止組播源或組播接收器傳送/接收流量。本節重點介紹如何驗證會影響組播源和組播接收方的問題，重點介紹與硬體程式設計無關的問題。

建立FHR (S，G)

要使FHR建立(S，G)驗證SISF、LISP、CEF和RPF是否全部有效並且正確，請使用命令「show device-tracking database address <IPv4 address>」

Edge-2#show device-tracking database address 10.47.7.3

LISP利用SISF，請使用命令「show lisp instance-id <L3 LISP Instance ID> ipv4 database <IP/32>」

LISP對CEF進行程式設計，請使用命令「show ip cef vrf <VN Name> <ip address>」，並確保它是VLAN中的下一跳，而不是指向LISP。

Edge-2#show ip cef vrf blue_vn 10.47.7.3

最後，請確保RPF指向正確，並且指示直接連線。

如果SISF/IPDT中沒有有效條目，則會導致FHR上沒有LISP資料庫對映，從而導致CEF和RPF指向邊框。如果組播源傳送流量，則RPF指向不正確的介面，這會導致RPF故障，(S，G)不會形成。

要避免這種情況，請將組播源視為靜默主機，在這裡，IP定向廣播、泛洪、靜態SISF/IPDT繫結可以解決此問題。

來源註冊

PIM註冊是一種單播資料包流，它像使用任何其他單播資料包一樣使用LISP/VXLAN。有幾個請求技術人員驗證FHR是否能夠將組播源正確註冊到任播RP。

首先，確保已為GDA正確配置任播RP。

Edge-2#show ip pim vrf blue_vn rp 239.0.0.5
Group: 239.0.0.5, RP: 10.47.6.1, uptime 1w4d, expires never

確保PIM暫存器隧道已形成。

Edge-2#show ip pim vrf blue_vn tunnel 
Tunnel1 
Type : PIM Encap
RP : 10.47.6.1 <-- This is from "ip pim vrf blue_vn rp-address 10.47.6.1 ASM_ACL_IPV4_blue_vn_10.47.6.1"
Source : 10.47.6.3 <-- This is from ip pim vrf blue_vn register-source Loopback4100
State : UP
Last event : Created (1w4d)

確保任播RP具有IP可達性

Edge-2#show ip cef vrf blue_vn 10.47.6.1
10.47.6.1/32
nexthop 10.47.1.10 LISP0.4100 <-- RLOC of Border-1
nexthop 10.47.1.11 LISP0.4100 <-- RLOC of Border-2

Edge-2#ping vrf blue_vn 10.47.6.1 source lo4100
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.47.6.1, timeout is 2 seconds:
Packet sent with a source address of 10.47.6.3 
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/3 ms

接收方驗證

確保組播接收方正在傳送IGMP MR。
確保啟用IGMP監聽。僅L2 VN是唯一未啟用IGMP監聽的VN型別
確保未配置可丟棄IGMP MR的埠ACL、VLAN ACL、路由埠ACL。
驗證IGMP MR的版本，預設情況下，如果組播接收器是IGMPv3，則需要「ip igmp version 3」
確保未配置「ip option drop」

LHR PIM (*，G)驗證

確保LHR是接收方子網/網段的PIM DR
確保未配置「ip組播組範圍」
確保未配置可丟棄IGMP MR的埠ACL、VLAN ACL、路由埠ACL。
確保沒有高CPU或控制平面管制(CoPP)丟棄IGMP MR。

LHR PIM共用樹狀結構驗證

確保為組配置了RP

Mroute硬體程式設計- FMAN FP資料庫

要驗證FMAN FP對象，請使用命令「show platform software object-manager switch active f0 object <object ID> parents」

例如，驗證覆蓋(*，G)

Edge-1#show platform software object-manager switch active f0 object 100880 parents 
Object identifier: 100605
Description: ipv4_mcast table 2 (blue_vn), vrf id 2
Status: Done
Object identifier: 100878
Description: mlist 109
Status: Done

驗證覆蓋(S，G)

Edge-1#show platform software object-manager switch active f0 object 161855 parents 
Object identifier: 100605
Description: ipv4_mcast table 2 (blue_vn), vrf id 2
Status: Done
Object identifier: 161854
Description: mlist 143
Status: Done

mlist是在不同對象中與mroute分隔的傳入介面(IIF)和傳出介面清單(OIL)的組合。要驗證mlist，請使用命令「show platform software mlist switch active f0 index <index>」

Edge-1#show platform software mlist switch active f0 index 109
