Hello All,
I'm performing task 7.4 (trying to use bridge-groups so that BB1 can talk to
BB3
across frame-relay), and I'm running into issues not documented in the solution
guide. Specifically, I cannot ping from BB1 to BB3 - or vice versa. After doing
a 'debug ip packet' on BB3, I noticed that encapsulation was failing and that
the arp entry for 100.100.100.100 was incomplete. After adding in the arp entry
manually on both BB1 and BB3, ping functions correctly. Is there something I'm
missing here, or is this expected behavior? I believe this is supposed to work
without manually adding in arp entries.
