Which Routing Protocol Process Am I Running?

Filed under: IOS,Tech Tips — cciepursuit @ 7:57 pm

So you’re in configuration mode and you’re ready to add a line to your BGP/OSPF/EIGRP process.  If you’re like me, you probably forgot which process/AS you’re running.  Was it “router eigrp 100” or “router eigrp 10”?  Here is a quick command you can run from configuration mode to find the answer to that question: “do show ip protocols summary”

r3#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
r3(config)#do sh ip proto sum
Index Process Name
0     connected
1     static
2     bgp 64563
3     ospf 100
4     eigrp 100

Finding out the BGP AS is even easier.  Just type in “router bgp x” where x is any number.  The router will tell you the correct AS:

r3(config)#router bgp 666
BGP is already running; AS is 64563

Command Reference:

show ip protocols [summary]
