Only ping to nonexisting node holds up a bridged link

The unordinary problem is: A connection over two 1720 (with WIC-1T) both acting as a bridge and working properly (tested with pinging stations on the other site) breaks down when a running ping to a nonexisting station is stopped. A firewall is installed on both site (at the e0 site of 1720). May be this occur the problem or inside the X.21?


Re: Only ping to nonexisting node holds up a bridged link

Often times complex troubleshooting issues are best addressed in an interactive trouble-shooting session with one of our trained technical assistance engineers. While other forum users may be able to help, it’s often difficult to do so for this type of issue.

To utilize the resources at our Technical Assistance Center, please visit and to open a case with one of our TAC engineers, visit

If anyone else in the forum has some advice, please reply to this thread.

Thank you for posting.

Re: Only ping to nonexisting node holds up a bridged link

A ping to a non-existing station would usually go to a default route. How is your routing and load defined to bring the bridge up (sorry not to familier with x.21). If you have a router defined for the other side of the link (or snapshot route), then the link would comeup whenever needed. A good idea would be to paste the configs of the two routers minus the password on this site.
