Issue:
When there is no traffic for a group, the LHR and RP take the default KAT+Join timer expiry of
a maximum of 480 seconds to clear the S,G . However, in the FHR, we update the state from JOINED
to NOT Joined, downstream state from PPto NOINFO. This restarts the ET timer, causing S,G on FHR to
take more than 10 minutes to age out.
In other words,
Consider a case where (S,G) is in Join state. When the traffic stops and the KAT (210) expires,
the Join expiry timer restarts. At this time, if we receive a prune, the expectation is to set
PPT to 0 (RFC 4601 sec 4.5.2).
When the PPT expires, we move to the noinfo state and restart the expiry timer one more time. We remove the
(S,G) entry only after ~10 minutes when there is no active traffic.
Summary:
KAT Join ET 210 + PP ET 210 + NOINFO ET 210.
Solution:
Delete the ifchannel when in noinfo state, and KAT is not running.

Just check to see if it has been allocated. The nexthop is a stack
variable so it's a bit odd.

Memory is being leaked when processing the eoiu marker.
BGP is creating a dummy dest to contain the data but
it was never freed. As well as the eoiu info was

In bgp_vpnv4_route_leak_basic, remove and add back the static prefix
172.16.3.0/24 on VRF DONNA. Before the previous fixes, the 172.16.3.0/24
prefix re-appeared when it was added back in the VPN table but it was
marked as invalid.

The bgp_bmp test is failing because r2 lacks the vrf1 VRF, which
prevents it from exporting VPN prefixes from the configured vrf1 BGP
instance. Previous versions allowed the export of static BGP prefixes
from a non-existent VRF, so the test passed under those conditions.
Add a vrf1 VRF on r2.

When leak_update() rechecks an existing path, it considers nothing to
update if the attributes and labels are not changed. However, it does
not take into account the nexthop validity.
Perform a leak update if the nexthop validity has changed.
