Router BGP command

In Cisco Student Guide, it says that the Router BGP command does not activate BGP. However, on my lab router, it shows this:

(config)#router bgp 5500

(config-router)#exit

(config)#router bgp 5600

BGP is already running; AS is 5500

Any idea?

Re: Router BGP command

Hello Wassim,

you cannot have a router on both BGP AS 5500 and BGP AS 5600 I usually use this to show this.

A BGP AS is owned by a company that got it from RIPE or ARIN (Regional Internet Registries)

And I agree with you once you enter router bgp 5500 the process is created.

Very good point

Hope to help

Giuseppe

It's running; the guide is incorrect.
