I am moving from Juniper to Cisco ( IOS XR ) and am looking to
emulate a certain feature ( aggregate addressing for BGP )
in XR you can use RPL for this.
In BGP on IOS XR you use the network statement network x.x.x.x/19 now
you need to have an exact route for this ( normally setting a static
route ). This will not suit my requirements as if we lose IGP on
that
router I would like to stop announcing the ranges via BGP but the
static route will still be there and I will theoretically blackhole
traffic.
Any ideas how to allow BGP to announce an aggregate route when there
is less specific in IGP would be a great help.
ASR(config-rpl)# if rib-has-route in (10.10.0.0/19 ge 20) then
ASR(config-rpl-if)# pass
ASR(config-rpl-if)# endif
ASR(config-rpl)
Then redistribute your static with "network 10.10.0.0/19 route-policy
foo"
inside of BGP.
