Re: No BGP Default route-target filter

Nope, just on the two routers you specified. The command stops P or PE
(depending on your network you may have multiple AS's) routers from dropping
VPNv4 prefixes they receive that they don't have configured locally in their
VRFs.

From a lab perspective I can't think of too many reasons (except the lab
telling you not to) not to configure it on each router - I tend to do it as
a habit. If I need routes filtered I'd rather filter them manually in the
lab.
