Symptoms

bgpd may crash on a BIG-IP system configured for dynamic routing announcing multiple overlapping aggregate-addresses with extended asn capabilities enabled.

Impact

Inability for the unit to use BGP

Conditions

- BGP enabled on route-domain - BGP configured to announce several overlapping aggregate-addresses - BGP configured with extended-asn-cap enabled.

Workaround

Disabling extended-asn-cap or not announcing multiple overlapping aggregate addresses may allow to workaround this issue.

Fix Information

bgpd no longer crashes with overlapping aggregate addresses and extended-asn-cap enabled
