Figure 13-33. Fixing a Misconfigured ACL
To fix the ACL so that Router A selects the correct RP for multicast group
239.255.255.200, you would enter these commands:
ProCurve(config)# ip access-list standard rp2
ProCurve(config-std-nacl)# no permit 224.0.0.0 15.255.255.255
Figure 13-34 shows another misconfigured RP set. The PIM domain in this
example uses the RP at 10.1.1.2 to support half of the multicast groups and
the RP at 10.3.3.2 to support the others. The administrator for Router A used
extended ACLs instead of standard ACLs and entered the group address as a
destination rather than a source. However, routers use the source address in
an RP's ACL to determine which groups the RP supports.
