pimd,yang: Extend multicast boundary functionality
Add new interface command ip multicast boundary ACCESSLIST4_NAME. This
allows filtering on both source and group using the extended access-list
syntax vs. group-only as with the existing "ip multicast boundary oil"
command, which uses prefix-lists. If both are configured, the prefix-
list is evaluated first. The default behavior for both prefix-lists and
access-lists remains "deny", so the prefix-list must have a terminating
"permit" statement in order to also evaluate against the access-list.
The following example denies groups in range 229.1.1.0/24 and groups in
range 232.1.1.0/24 with source 10.0.20.2:
!
ip prefix-list pim-oil-plist seq 10 deny 229.1.1.0/24
ip prefix-list pim-oil-plist seq 20 permit any
!
access-list pim-acl seq 10 deny ip host 10.0.20.2 232.1.1.0 0.0.0.255
access-list pim-acl seq 20 permit ip any any
!
interface r1-eth0
ip address 10.0.20.1/24
ip igmp
ip pim
ip multicast boundary oil pim-oil-plist
ip multicast boundary pim-acl
!
