I seem to be experiencing a problem with dropped packets. The internal network here is a class A 10.x.x.x scheme which is then connected to a class C colocations on a 156.x.x.x scheme. The ethernet side of the router on the class A network is 10.111.111.111 the serial side is 172.16.1.1. On the router at the colocation the IP is 184.108.40.206 and the serial is 172.16.1.2.
If I ping with a packet size as low as 500 I get intermittent drops whether I'm pinging from the class A to the class C network or vice versa. Some times it even drops packets with the default packet size of 32. I checked my routes but am still unable to figure out the issue. Here is the setup on the router at the class A side followed by the Class C side config.
You were right. I fixed that but am still having the same issues. On the Class A side here is the show int e 0/0. It has CRC errors on input. There are no errors on the serial side. I did have a few errors on the Class C side but not since I cleared the counters about an hour ago. Here is the ethernet side of the Class A side router:
Ethernet0/0 is up, line protocol is up
Hardware is AmdP2, address is 0008.a370.1680 (bia 0008.a370.1
Internet address is 10.111.111.111/8
MTU 1500 bytes, BW 10000 Kbit, DLY 1000 usec,
reliability 255/255, txload 2/255, rxload 2/255
Encapsulation ARPA, loopback not set
Keepalive set (10 sec)
ARP type: ARPA, ARP Timeout 04:00:00
Last input 00:00:00, output 00:00:00, output hang never
Last clearing of "show interface" counters 00:48:28
I forced the duplex to half-duplex on both ethernet sides and this seemed to fix the issue. When you to a show int e 0/0 it doesn't show you what it is set to. I thought it might be this because I telnetted to the Class A router and pinged a Machine on the Class A network and it got time outs. Once I changed the duplex I'm not dropping packets.
I tried setting both ethernet sides to full duplex but started dropping packets again. I guess I'm going to have to stick with half-duplex.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
