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.

    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"
    Sending updates every 30 seconds, next due in 4 seconds
    Invalid after 180 seconds, hold down 180, flushed after 240
    Outgoing update filter list for all interfaces is not set
    Incoming update filter list for all interfaces is not set
    Redistributing: rip
    Default version control: send version 1, receive any version
    Interface Send Recv Triggered RIP Key-chain
    FastEthernet0/0 1 2 1
    Serial0/0/1 1 2 1
    Serial0/0/0 1 2 1

    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.
