Hello group,

Any takers ?

I dind't find any documentation saying that discontiguous wildcard mask
are/are not supported. If they are supported, i still would like to know if
they may applied to Auto-RP, BSR or Static-RP.

Thanks.
Antonio

Dear Group,

When defining Mcast Groups using Auto-RP or BSR are we allowed to use
discontiguous Wildcard Marks ?

For example, i have this in my lab:

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

R3:
!
ip access-list standard mcast
 permit 225.10.0.0 0.48.255.255
!
ip pim send-rp-announce Loopback0 scope 16 group-list mcast
ip pim send-rp-discovery Loopback0 scope 16

R4:
!
ip access-list standard mcast
 permit 226.37.0.0 1.8.255.255
!
ip pim send-rp-announce Loopback0 scope 16 group-list mcast
ip pim send-rp-discovery Loopback0 scope 16

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

And i see mappings to 225.10.0.0/22 and 226.36.0.0/14 which are different to
the ACL's defined:

Rack1R2(tcl)#sh ip pim rp map
PIM Group-to-RP Mappings

Group(s) 225.10.0.0/22
  RP 150.1.3.3 (?), v2v1
    Info source: 150.1.4.4 (?), elected via Auto-RP
         Uptime: 00:26:21, expires: 00:02:29

Group(s) 226.36.0.0/14
  RP 150.1.4.4 (?), v2v1
    Info source: 150.1.4.4 (?), elected via Auto-RP
         Uptime: 00:23:41, expires: 00:02:30
Rack1R2(tcl)#

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

The only option here is to use Static RP ?

Thanks.
Regards,
Antonio
