Is it possible to see multiple routing protocols on a router?

like "show ip protocols"? Will the lately configured always flush the previous ones?

#show ip protocols || #show ip protocols summary should always show the current running Connected, Static, IGP, and EGP protocols running on the device:
R1#sh ip proto summ
Index Process Name
0 connected
1 static
2 ospf 1
3 eigrp 100
4 bgp 32385

You can definitely have multiple routing protocols running at the same time. That's where Administrative Distance comes in.. so if the router learns about a network through EIGRP (AD of 90), and learns about the same network through OSPF (AD of 110), than the EIGRP route will make it in the routing table.Currently reading: Internet Routing Architectures by Halabi -

my ios is 12.4. Hmmm. summary is not supported...
Also, it seems "sh ip proto" does not give me the "connected" part.Router#sh ip proto
Routing Protocol is "rip"

Yes, you can have multiple protocols on the same router, you can use it as border router or to redistribute one protocol in another.
I used it only when I need to make conection between one network runnning Eigrp and another running RIP or OSPF.
