[j-nsp] BGP Configuration on J6350

[Eric Van Tol]

Try doing a 'show route advertising-protocol bgp x.x.x.x', where x.x.x.x
is the GSR address.  It's quite possible that it is already sending a
full table and the GSR just isn't showing the inactive routes.  I can't
remember what the default behavior is of Cisco, in terms of showing
routes received in 'show ip bgp summary'.

If you want to be sure, however, you can do the following:

policy-statement internal {
    term term1 {
        from protocol bgp;
        }
        then nexthop self;
    }
}

That will re-advertise all routes learned through BGP to any peer on
which you've applied this policy.
