ISDN Dropping Half of Ping attempts

[pdecker]

Currently my set up is two routers (A and B), each connected to an ISDN line, and each with its own network. T

Router A dials Router B, connects, and data can transfer between the two networks (A and B). For some reason though, when I ping router B's network from router A's network, half of the ping attempts time out. So it alternates and looks like

Request timed out.

Request timed out.

Any ideas as to why this is occuring? any ideas as to how to fix it? The whole setup is for experimental purposes so the two ISDN lines are right next to each other in the same room . Thanks,

looks like load balancing!!! what does a trace route show?

This is the trace route from a workstation in network A to the ISDN BRI interface in router B across the ISDN connection:

10.16.10.153 is router A's fastethernet connection to network A.
172.17.20.2 is router B's BRI interface to the ISDN line.

Tracing route to 172.17.20.2 over a maximum of 30 hops

1 <10 ms <10 ms <10 ms 10.16.10.153
2 * 30 ms * 172.17.20.2
3 * 30 ms * 172.17.20.2
4 * 30 ms * 172.17.20.2
5 30 ms * 30 ms 172.17.20.2

Trace complete.

I dont realy know how to read these results, never really used trace route before. If it is load balancing, what would I do to correct the problem, or where could I find information on load balancing? Thanks for your help.
