hi all,
i have a problem regarding multicast bidir redudency RP.
as we know the redudency RP with bidir is created by the PHNTOM RP-
"The preferred method for providing Bidir rendezvous point redundancy can be designed using
loopback networks with different mask length . This mechanism relies on unicast routing longest
match route lookups to guaranteea consistent path to the rendezvous point"
in the new IOS image (I.E router 3945), when we create a loopback, the router will install L route (which is host /32 route).
beacause of the /32 route the PHANTOM RP can not work properly.
=====================================
R1_BACKUP_RP# interface Loopback2
description RP_address
ip address X.X.200.1 255.255.255.0
ip pim sparse-mode
R1_BACKUP_RP#sh ip route
L x.x.200.1/32 is directly connected, GigabitEthernet0/1
=====================================
the x.x.200.1/32 address is the ip of the master RP but beacuse of that L route
the pim can creat the shrade tree as it should.
anyone can verify?
