Dear All,

IN Cisco IOS, is there is seperated Scanners one for BGP and another one for MP-BGP!!! i beleive that because there is onlyBGP process per router so Practically there is only One Scanner also the output of show proc cpu | inc BGP shown that there is only one scanner running on the router while the router running BGP and MP-BGP session

155 4853192 28039604 173 0.00% 0.02% 0.00% 0 BGP Router

157 1834796 3016664 608 0.00% 0.01% 0.00% 0 BGP I/O

Re: BGP Scanner

Mounir,

There is indeed one scanner for all address families.

Hope this helps,

Re: BGP Scanner

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.
