Mounir,

There is indeed one scanner for all address families.

Hope this helps,

Hello,

there is one Scanner process in software, but you can instruct it to scan different address-families at different frequencies. The config could be like this (not complete for a PE, just to show bgp scan-time):

router bgp 65000

bgp scan-time 20

neighbor 10.1.1.1 remote-as 65000

address-family vpnv4

neighbor 10.1.1.1 activate

neighbor 10.1.1.1 next-hop-self

bgp scan-time 15

exit-address-family

Hope this helps! Please rate all posts.
