RSRB: Host Cannot Connect to Server (Peers Open)
RSRB: Host Cannot Connect to Server (Peers Open)
Symptom: Hosts cannot make connections to servers across a router configured as an RSRB. The
output of the show source-bridge privileged exec command shows that SRB peers are open.
The following is an example of output from the show source-bridge command:
ionesco#show source-bridge
[...]
Peers: state lv pkts_rx pkts_tx expl_gn drops TCP
TCP 150.136.92.92 - 2 0 0 0 0 0
TCP 150.136.93.93 open 2* 18 18 3 0 0
[...]
Table 10-4 outlines the problems that might cause this symptom and describes solutions to those
problems.

Possible Problem Solution
End system
misconfiguration
Step 1 If the end system is on the ring local to the router, use the show lnm station
privileged exec command on the local router. This command lists the stations on
the local ring.
The following is an example of the show lnm station command:
show lnm station [address]
Syntax Description:
• address—(Optional) Address of a specific LNM
1
station.
Sample Display:
The following is sample output from the show lnm station command when a
particular address (in this case, 1000.5abc15) has been specified:
Router# show lnm station 1000.5a6f.bc15
