Subject: GRE devices and MULTICAST flag.
Date: Fri, 23 Sep 2011 12:56:35 -0700 [thread overview]
Message-ID: <4E7CE473.3000304@candelatech.com> (raw)
I was under the impression that GRE tunnels could support MULTICAST
traffic, but the MULTICAST flag is not set. This is making the xorp
router crap out because it checks the MULTICAST flag and will
not start multicast on the interface if it's not set....
Is it supposed to be set?

link/gre 192.168.100.223 peer 192.168.100.138
inet 10.0.1.1/32 scope global netb
Thanks,
Ben
