Cisco Catalyst 2960-XR Configuration Guides

If you have non-Cisco PIMv2 routers that need to interoperate with Cisco PIMv1 routers and multilayer
switches, both Auto-RP and a BSR are required. We recommend that a Cisco PIMv2 router or multilayer
switch be both the Auto-RP mapping agent and the BSR.
If you must have one or more BSRs, we have these recommendations:
•
Configure the candidate BSRs as the RP-mapping agents for Auto-RP. For information about these
procedures, see:
◦
Configuring a Rendezvous Point, on page 47
◦
Configuring Candidate BSRs, on page 61
•
For group prefixes advertised through Auto-RP, the PIMv2 BSR mechanism should not advertise a
subrange of these group prefixes served by a different set of RPs. In a mixed PIMv1 and PIMv2 domain,
backup RPs should serve the same group prefixes. This prevents the PIMv2 DRs from selecting a different
RP from those PIMv1 DRs, due to the longest match lookup in the RP-mapping database.
Before You Begin
Beginning in privileged EXEC mode, follow these steps to verify the consistency of group-to-RP mappings.
This procedure is optional.
SUMMARY STEPS
1.
show ip pim rp [ hostname or IP address | mapping [ hostname or IP address | elected | in-use ] | metric
[ hostname or IP address ] ]
2.
show ip pim rp-hash group
DETAILED STEPS
PurposeCommand or Action
On any Cisco device, displays available RP mappings and metrics:
show ip pim rp [ hostname or IP address |
mapping [ hostname or IP address | elected |
in-use ] | metric [ hostname or IP address ] ]
Step 1
•
(Optional) For the hostname, specify the IP name of the group about
which to display RPs.
Example:
Switch# show ip pim rp mapping
•
(Optional) For the IP address, specify the IP address of the group
about which to display RPs.
•
(Optional) Use the mapping keyword to display all group-to-RP
mappings of which the Cisco device is aware (either configured or
learned from Auto-RP).
•
(Optional) Use the metric keyword to display the RP RPF metric.
On a PIMv2 router or multilayer switch, confirms that the same RP is the
one that a PIMv1 system chooses.
show ip pim rp-hash group
Example:
Switch# show ip pim rp-hash 239.1.1.1
Step 2
For group, enter the group address for which to display RP information.
