We're running MSFC with the IOS ver 12.1(13)E6 inside the Cat-6505. The IP Source Routing is not explicitly disabled in the config. I have not been able to determine if Cisco has enabled it by the default. Is there a way to tell whether or not the IP Sourse Routing is enabled on these MSFC's?
Thanks.

Alex,
By IP source routing I assume you mean can will the device route packets for networks that it knows about. If that is the question then the answer is that IP routing is enabled by default on the MSFC. You can determine this by issuing the command "show ip route". If the MSFC returns something like this:
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is not set
C 127.0.0.0/8 is directly connected, EOBC0/0
That is an indication that ip routing is enabled. If it looks like this:
Router#sh ip route
Default gateway is not set
Host Gateway Last Use Total Uses Interface
ICMP redirect cache is empty
That is an indication that IP routing has been disabled.
If this is not what you are looking for then let me know and we'll try again.

Steve,
Thanks for your response. Our default gateway is in fact set. However, I would still like to disable the IP source routing for security reasons. I just wanted to make sure it was enabled by default.

I suggest you to disable this feature, it will written explicitly in the config.
mpls-t#sh run | inc source-rout
no ip source-route
Hope this helps

Phil, thanks for your response. Why do you suggest to disable the IP source routing?
