To determine if IS-IS point-to-point link is being used by ISs, use the show isis neighbor command.
In the example below, the line in bold identifies a point-to-point configuration on the XMR1 system
for the gre_tnl 1 interface.
You can use the show ip route isis command to determine if next hop is a tunnel. For example.
IS-IS Non-Stop Routing
Overview
NOTE
IS-IS Non-Stop Routing (NSR) is applicable only to IPv4 routes computed by IS-IS and does not apply
to IPv6 routes.
NOTE
IS-IS NSR is not supported on the Brocade NetIron CES and Brocade NetIron CER platforms.
