no ip redirects command

[insubliminal]

Hello,

I have a 2610 as the local LAN router plugged into a switch. There is also a MPLS 2820 Cisco router plugged into the switch. I also have a PIX 501 plugged into the switch with inside int as 192.168.2.253 and a tunnel out. The e0/0 of the 2610 is 192.168.2.254 and the fa0/0 int of the 2820 is 192.168.2.1. Everyones PC on the LAN has their gateway as the 2610 router which is 2.254. the 2610 default route out is the 2820. Now the 2820 has the "no ip redirects" command enabled on the fa0/0 int. My problem is, when I enable the "no ip redirects" on the 2610, the LAN all of a sudden becomes slow and the 2610 starts spitting out hundreds of CRC errors. When I take the command out, everything works fine. Can someone please explain why this may happen? I really need the "no ip redirects" command on this router because with out it, when I make a route change on the 2610, it takes a long time to process the route to all PC's because they are being redirected still by the 2610 when I want it to happen immediately to point to the PIX. Thanks,

Jimmy K

Ok, I think I found my problem I believe it is a duplex mismatch that causes this problem though I am facing a dillema. The 2610 is set to full-duplex and the interface is 10MB. The 2950 switch of course has all 10/100 ports and the port the 2610 is plugged into is on auto detect and detects it at Half 10MB. On the 2610, the int e0/0 has it running at full-duplex. How can I make the 2950 run at full 10MB? I change the switch port to FULL and all of a sudden both interfaces go down. How can I keep it at FULL? Half works fine but I do not want that. Someone please help. Thanks,

It should just be the below config, if not then I have seen on some these older 2600's where the full duplex command is there but does not really work and you have to run it at half duplex , just no way around it . If the line goes down when you hardcode the 2950 then that is what you are probably running into .

interface x/x
speed 10
duplex full
