When the MAX brings up the two Frame Relay PVC, the routing table includes entries such as
this:
...
10.168.7.0/24 10.168.7.9 wan33 rGT 60 1 0 89
10.168.7.0/24 10.168.7.9 wan33 *SG 120 7 0 198
10.168.7.9/32 10.168.7.9 wan33 rT 60 1 0 89
10.168.7.9/32 10.168.7.9 wan33 * 120 7 198
10.168.7.11/32 10.168.7.11 wan32 rT 60 1 0 51
10.168.7.11/32 10.168.7.11 wan33 *S 120 1 89
...
At this point, both nailed connections are up, and the output of the Ifmgr command contains
entries such as the following:
bif slot sif u m p ifname host-name remote-addr local-addr
--------------------------------------------------------------------
032 1:03 001 * p wan32 pvc 10.168.7.11/32 11.168.6.234/32
033 1:03 002 * p wan33 fp7 10.168.7.9/32 11.168.6.234/32
If the primary PVC becomes unavailable, the routing table does not change, but the entries in
the output of the Ifmgr command look like the following output:
bif slot sif u m p ifname host-name remote-addr local-addr
--------------------------------------------------------------------
032 1:03 001 * p wan32 pvc 10.168.7.11/32 11.168.6.234/32
033 1:17 000 + p wan33 fp7 10.168.7.9/32 11.168.6.234/32
Notice that fp7 is shown with a plus-sign (+) to show that it is in the Backup Active state (that
it is backed up by another connection). When the primary PVC comes up again, the data flow
is directed to that interface again. At that point, the Ifmgr command output again shows both
interfaces as up.
