Sometimes there are multiple ways to do things. If we
only want to get 7500 and its neighbors, I'd use
^7500_[0-9].*$:
route-views.oregon-ix.net>sh ip bgp regex
^7500_[0-9].*$
BGP table version is 4458991, local router ID is
198.32.162.100
Status codes: s suppressed, d damped, h history, *
valid, > best, i - internal
Origin codes: i - IGP, e - EGP, ? - incomplete
