[44net] router stats

The ipip router at UCSD is not very busy (99% idle), but I am surprised at the number of dropped packets. It's higher than I would have hoped, suggesting there are a significant number of misconfigured routers on the network. - Brian ------------------------------------------------------------------ started at Tue May 2 20:49:25 2017 snapshot at Tue May 2 22:00:00 2017 uptime: 0+01:10:35 (4235 seconds) idle: 4194.615196 secs (99%) packets/bytes ---------/--------- 181908/50252930 ipip encapped input 170575/45757610 forwarded out unencapsulated 1/56 dropped: no source gateway 1666210/125325363 unencapsulated input 1666196/125324029 encapped out 0/0 dropped: no destination gateway 5994/447291 dropped: encap to encap 0/0 ttl exceeded 0/0 icmp sent 0/0 dropped: packet too large 0/0 dropped: zero outer source address 0/0 dropped: broadcast outer destination address 0/0 dropped: packet too short 0/0 dropped: zero inner source address 481/66757 dropped: broadcast inner destination address 13/676 dropped: multicast inner destination address 4781/337160 dropped: non-44 inner source address 0/0 dropped: embedded encap protocol 35/1400 dropped: ip_len > MTU and DF 0/0 dropped: ip_len != packet size 0/0 dropped: output packet too short 0/0 dropped: output packet too long 4181/347878 dropped: output blocked by firewall 1/40 dropped: kernel send error 0/0 dropped: multicast inner source address 1171/1756463 outgoing encapped IPIP packet will be fragmented by kernel 2019413 route lookups took 1782499 microseconds (0.88 usec/lookup) 2 route table updates took 0.008852 seconds (4 msec each avg)
