[c-nsp] xconnect problem between C7606

[jure brkljacic]

Hi,

Thanks for help. I do not have the access to BGP router (the "picture" from
the first mail)

IPv4 broadcast should be working. ARP resolution OK, IP reachability OK,
BGP neighbor OK.
How to check if IPv4 multicast is working in both directions without the
access to BGP router?
