Subject: Practical Study2 Lab6: group-list doesn't work
Hi group,
the group-list for R13 as suggested in the book doesn't work and r13
becomes the RP for all 224.0.0.0/4
See here:
r13 loopback = 192.168.255.13
r5 loopback = 192.168.255.5
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
r13
ip pim send-rp-announce Loopback0 scope 16 group-list 8
access-list 13 deny 239.0.0.0 0.255.255.255

To achieve the goal of having R13 for 'all multicast groups, except
administratively scoped addresses' I had to rewrite the ACL in the
following funny way !! It seems that the 'deny' it is not taken
correctly. Any idea?
r13
ip pim send-rp-announce Loopback0 scope 16 group-list 7
