Default Multicast Routing Configuration
Table 44-2 shows the default multicast routing configuration.
Multicast Routing Configuration Guidelines
To avoid misconfiguring multicast routing on your switch, review the information in these sections:
• PIMv1 and PIMv2 Interoperability, page 44-11
• Auto-RP and BSR Configuration Guidelines, page 44-12
PIMv1 and PIMv2 Interoperability
The Cisco PIMv2 implementation provides interoperability and transition between Version 1 and
Version 2, although there might be some minor problems.
You can upgrade to PIMv2 incrementally. PIM Versions 1 and 2 can be configured on different routers
and multilayer switches within one network. Internally, all routers and multilayer switches on a shared
media network must run the same PIM version. Therefore, if a PIMv2 device detects a PIMv1 device,
the Version 2 device downgrades itself to Version 1 until all Version 1 devices have been shut down or
upgraded.
PIMv2 uses the BSR to discover and announce RP-set information for each group prefix to all the routers
and multilayer switches in a PIM domain. PIMv1, together with the Auto-RP feature, can perform the
same tasks as the PIMv2 BSR. However, Auto-RP is a standalone protocol, separate from PIMv1, and
is a proprietary Cisco protocol. PIMv2 is a standards track protocol in the IETF. We recommend that
you use PIMv2. The BSR mechanism interoperates with Auto-RP on Cisco routers and multilayer
switches. For more information, see the
“Auto-RP and BSR Configuration Guidelines” section on
page 44-12 .
