Thanks to everyone who helped...... It ended up being a Telco problem. Something about a protocol mismatch...... Kind of like a half / full duplex issue with Frame-relay / ATM.

Well, the ATM side should happily work with whatever MTU you configure, as long as both sides are the same (telco never sees the full packet, only ATM cells). The ATM FR interworking might be a problem, with the ATM side defaulting to an MTU of 4470 and the FR side being Telco-limited to 1500 (or whatever). For transit traffic coming via Ethernet into the router, this is not a problem (as the packets are already "small") - but for traffic generated *by* the router, it might be. > > ATM side: > > > > interface ATM4/0/0.134 point-to-point > > bandwidth 1024 > > ip address 172.20.2.13 255.255.255.252 Try putting: ip mtu 1500 (or plain "mtu 1500") in here. > > Frame side: > > > > Serial 0/0 > > Encapsalation Frame-Relay ietf > > No ip add > > > > Serial0/0.16 point > > Ip add 172.20.2.14 255.255.255.252 > > Frame-relay interface-dlci 16 ... and for symmetry, do the same on this side (dunno what the default MTU for FR interfaces is). gert -- USENET is *not* the non-clickable part of WWW! //www.muc.de/~gert/ Gert Doering - Munich, Germany [EMAIL PROTECTED] fax: +49-89-35655025 [EMAIL PROTECTED] _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
