Help - Want to pass data from 1 ATM port to another, same Router

Hello,

I am trying to send data from GigE1 to ATM1/0 to ATM2/0 to GigE2. My real intent is to send Multicast data, but have since backed out the Mulitcast commands, just focusing on getting ICMP pings to pass. My configuration is as follows:

Current configuration : 1776 bytes

I'm trying ot force the data from the GigE1 to ATM1/0, then force from ATM1/0 to ATM2/0, then ATM2/0 to GigE2. With this configuration, I am not seeing any data using the show atm traffic.

Can anybody help?

Thanks,

Bruce

Sorry, all references to GigE2 is actually GigE3

Re: Help - Want to pass data from 1 ATM port to another, same Ro

There are some obvious errors in your config.

Firstly, under the ATM interfaces, you have to use the 'protocol ip' command to specify addresses of other devices reachable through the interface, not the local IP address.

Secondly, the 'match interface' command is not required in your route-maps - it will match on packets that are routed out of the specified interface which is not what you want.

Thirdly, in your route-maps, use the 'set ip next-hop' command to specify the IP of a router reachable through the interface, not a local interface IP.

Hope that helps - pls rate the post if it does.
