Hi all,

Refering to below config. can router advertise 148.50.0.0/16 to outside, Since as i know, router can only advertise route

when the interface subnet mask is exactly match with subnet mask under router bgp xxx. But now the two subent mask are not

match (148.50.1.253/24, 148.50.0.0/16). So can router advertise 148.50.0.0/16 to outside

Hello,

yes if one of the following actions is done

a) you enable auto-summary under router bgp

b) you create an aggregate for the net under router bgp but take care to have at least a component subnet in the BGP table

Hope to help

Giuseppe
