configure msdp max-rejected-cache

configure msdp max-rejected-cache max-cache {vr vrname}


Configures the maximum limit on rejected SA cache entries that an MSDP router will store in its database.

Syntax Description

max-cache Specifies the maximum number of rejected SA cache entries that the MSDP router will store in its database. To remove the limit, enter 0 (zero) for the max-cache value.
vrname Specifies the name of the virtual router to which this command applies. If a name is not specified, it is extracted from the current CLI context.


By default, the maximum cache entries stored is zero. That is, rejected SA cache entries are not stored. Any SA cache entries that are stored and not refreshed for six minutes are removed.

Usage Guidelines

SA cache are rejected because of:
  • Peer-RPF failure
  • Policy denied

When a previously rejected SA cache entry is accepted because of an RP reachability change or policy rule change, the rejected SA cache entry is moved to the accepted SA cache list.

By default, rejected SA cache entries are discarded. You can configure a limit for rejected cache entries to store them, which will help debug/diagnose some issues; however, it consumes extra memory.


The following command sets the maximum rejected cache limit to 100 for an MSDP router:

configure msdp max-rejected-cache 100
