Show BGP
The show bgp attach point allows the user to display selected BGP routes that pass the given policy. Any
routes that are not dropped by the attached policy are displayed in a manner similar to the output of the show
bgp command.
In the following example, the show bgp route-policy command is used to display any BGP routes carrying
a MED of 5:
route-policy sample-display
if med eq 5 then
pass
endif
end-policy
!
show bgp route-policy sample-display
A show bgp policy route-policy command also exists, which runs all routes in the RIB past the named policy
as if the RIB were an outbound BGP policy. This command then displays what each route looked like before
it was modified and after it was modified, as shown in the following example:
show rpl route-policy test2
route-policy test2
if (destination in (10.0.0.0/8 ge 8 le 32)) then
set med 333
endif
end-policy
!
