I have a problem exchanging routing information between a VAX 11/750 running GATED version 2.0.1.4 and a cisco. This is our machine configuration: ------------ ---------- | VAX | | cisco | milnet----+ +--local ethernet---+ +----X.25 to other nets 26.0.0.0 | | 192.26.147.0 | | ------------ ---------- The cisco exchanges routes with other ciscos via IGRP. The VAX exchanges routes with the core using EGP (obviously). Both the cisco and the VAX broadcast default routes over the ethernet using RIP. Our first inclination was to exchange routes using BGP. However, the cisco would not allow redistributing the BGP routes into IGRP. So, we decided to exchange routes via HELLO. Gated on the VAX sees the cisco's hello packets just fine, but the cisco does not like gated's packets at all. A "debug ip-hello" on the cisco produces: HELLO: bad checksum from 192.73.3.1 in response to gated's packet: Dec 4 10:47:18 HELLO SENT 192.73.3.1 -> 192.73.3.5 20 bytes 1 nets HELLO SENT unsync 12/4/90 18:47:20.232 GMT tstp 0 HELLO SENT type 1 count 1 HELLO SENT 26.0.0.0 delay 1 offset 0 The ethernet interface on the VAX is OK, so I do not (presently) suspect hardware to be the culprit. The following is the relavant portions of the gated.conf file: hello pointopoint { defaultmetric 5 ; interface 26.5.0.103 192.26.147.1 nohelloin nohelloout ; sourcegateways 192.73.3.5 ; } ; accept proto hello { listen 192.73.3.1 ; } ; propagate proto hello { proto egp as 164 { announce all ; } ; proto direct { announce 26.0.0.0 metric 1 ; } ; } ; And from the cisco configuration: router hello distribute-list 3 out default-metric 200 network 131.131.0.0 network 192.26.147.0 network 192.73.3.0 redistribute igrp 131 neighbor 192.73.3.1 passive-interface Ethernet0 passive-interface Serial0 Any suggestions/bugfixes are appreciated.
