Re: Re: [Idr] why has 4096 bytes limit on BGP messages size?

Then why not other limit,how is 4096 bytes derived, thanks.BTW,whether it's a good pratice in protocol devise to limit message sizes?I see in ripV1 that the maximum PDU length is 576bytes its reason is to avoid IP fragmentation,but in ripng the PDU length is determined only by the link MTU,and in snmp i also doesn't see the message size limit.
