pimd: add peerlink-rif to the origination-mroute's OIL
In a PIM MLAG setup (say L11<->L12 is the anycast VTEP pair) the RP
can choose to join either MLAG switch as the anycast VTEP-IP is
present on both. Let's say the RP joins L11.
Hosts are dual connected to L11<->L12 and can send traffic to either
switch. Let's say a host sends broadcast traffic to L12; now L12
must encapsulate and send the traffic toward L11. To do that the
origination-mroute on L12 must include the ISL in its OIL -
(36.0.0.9, 239.1.1.100) Iif: peerlink-3.4094 Oifs: peerlink-3.4094
L11 has a similar mroute -
(36.0.0.9, 239.1.1.100) Iif: peerlink-3.4094 Oifs: peerlink-3.4094 uplink-1
This mroute is used to rx traffic on peerlink-3.4094 and send it out of
uplink-1. Note that this mroute also includes the peerlink-rif in its
OIL. Explicit removal of IIF from OIL is done by the kernel (and other
dataplanes) to prevent traffic looping.
