MP-BGP

Hello.

I have a question. Does BGP send multiprotocol updates with usual IPv4 updates or separately? Coz I dont understand  MP_REACH_NLRI attribute. It is a part of usual BGP updates or separate update?

Hi Volodymyr,

Each address family update message will be sent separately as their can be only one MP_REACH_NLRI AF type per update message.

The packet structure for each family of protocol/NLRI is different for Updates. All are Updates but catering for different data structures.

Thanks.
