PROBLEM: 7301 dropping OSPF adjacencies. The log is showing the following messages:
Apr 23 12:20:01 c7301 392: 000398: Apr 23 12:20:00.016 PDT: %OSPF-5-ADJCHG: Process 5794, Nbr x.x.x.x on GigabitEthernet0/0 from LOADING to FULL, Loading Done Apr 23 12:20:01 c7301 393: 000399: Apr 23 12:20:00.016 PDT: %OSPF-5-ADJCHG: Process 5794, Nbr x.x.x.x on GigabitEthernet0/1 from LOADING to FULL, Loading Done During this, all traffic moves over to my other router. BGP peers stay up, but IGP routes get dumped. The router sees about 200M and 30k PPS on each interface at peak times. CPU gets to about 55% at peak. This issue is occurring near, but not always at peak. Code is older, disk0:c7301-js-mz.123-14.T3.bin. But this issue just started showing up. It has me a bit concerned as we just had a series of power events with a misbehaved UPS. I can ping the multicast address fine: wsc-rtr-7301#ping 224.0.0.5 Type escape sequence to abort. Sending 1, 100-byte ICMP Echos to 224.0.0.5, timeout is 2 seconds: Reply to request 0 from lo.bdr1.fqdn (x.x.x.x), 1 ms Reply to request 0 from ge-1-0-6.agr1.fqdn (x.x.x.x), 4 ms Reply to request 0 from ge-0-2-v100.bdr1.fqdn (x.x.x.x), 1 ms wsc-rtr-7301#sh ip os n Neighbor ID Pri State Dead Time Address Interface x.x.x.x 255 FULL/DR 00:00:06 x.x.x.x GigabitEthernet0/0 y.y.y.y 25 FULL/BDR 00:00:07 x.x.x.x GigabitEthernet0/1 The interfaces includes the following: int gi0/0 ip ospf hello-interval 2 ip ospf priority 25 ip ospf retransmit-interval 1 int gi0/1 ip ospf hello-interval 2 ip ospf priority 30 ip ospf retransmit-interval 1 Thank you in advance for any help. -b -- Bill Blackford Senior Network Engineer NWRESD my /home away from home _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
