Hi.
I hope this mailinglist is still active.
I am using Zebra, eBGP, Pimd version 0.99.25-dev so far and everything is working.
eBGP is getting the routes from the neighbors over physical and logical interfaces (GRE).
Zebra is writing these routes into the kernel and pimd is getting the next hop via pim_zlookup.
Example:
2017/01/23 10:48:59 PIM: pim_zlookup.c zclient_lookup_nexthop: lookup=0/3: zebra returned recursive nexthop 172.26.79.4 for address 10.6.7.25 dist=20 met=0
I tried to upgrade to version 1.1.0 at the weekend.
The routes are there, also mroutes. "show ip rib XXXX" is showing the right outgoing interface, but the next hop is always 0.0.0.0
I do not see any pim_zlookup in the logs, just

But the BGP routes are there.
If I configure static routes, the next hop is populated and multicast routing is working.
Maybe someone can help?
