cef adjacency route override rib

To enable the CEF prefer Routing Information Base (RIB) prefixes over Adjacency Information Base (AIB) prefixes in the Global configuration mode. To enable the CEF prefer AIB prefixes over RIB prefixes, use the no form of this command.

cef adjacency route override rib

no cef adjacency route override rib

Syntax Description


route	Enables adjacency route configuration .
override	Sets override options for the adjacency routes.
rib	Sets options for adjacency routes to override the RIB routes.

Command Default

By default, CEF prefers RIB prefixes over AIB prefixes.

Command Modes

Global configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

CEF may prefer the L2 adjacency for forwarding over the RIB (routing) entry under the following conditions:

When there is no local ARP entry (yet).

ARP learning may result in the router creating a forwarding entry.
A forwarding entry of /32 (or /128 for IPv6) RIB routes are overridden when there is a covering connected or attached route.

If an interface has a larger subnet, and you want to redirect a /32 out of that subnet of a different interface via a static route.

To deviate from the behavior of preferring a L2 adjacency for forwarding over a route entry, use the cef adjacency route override rib command.

show cef ipv6 drops

To display IPv6 Cisco Express Forwarding (CEF) table packet drop counters, use the show cef ipv6 drops command in XR EXEC mode.

show cef [vrf vrf-name]ipv6 drops [location node-id]

Syntax Description


vrf	(Optional) Displays VPN routing and forwarding (VRF) instance information.
`vrf-name`	(Optional) Name of a VRF.
location `node-id`	(Optional) Displays IPv6 CEF table packet drop counters for the designated node. The `node-id` argument is entered in the rack/slot/module notation.

Command Default

No default behavior or values

Command Modes

XR EXEC mode

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

A packet might be dropped by the IPv6 CEF table because of unresolved CEF entries, unsupported features, absence of route information, absence of adjacency information, or an IP checksum error.

If you do not specify a node with the location keyword and node-id argument, this command displays the packet drops for all nodes.

Note

Because no hardware forwarding occurs on the route processor (RP), no packet drop information is displayed for that node.
