Negotiating the BGP Version

BGP peers negotiate the version of BGP that they will use to exchange routing

information. If you enable both BGP-3 and BGP-4, the router first attempts to use

BGP-4. If the BGP peer is not a BGP-4 speaker, the router uses BGP-3.

By default, BGP considers BGP-4 as both the minimum and maximum acceptable

version for negotiation.

You can use the BCC or Site Manager to specify BGP-3 as the minimum or

maximum acceptable version.

Using the BCC

To specify the minimum version, go to a BGP peer prompt

box; ip;

/jointfilesconvert/97454/bgp; peer/2.2.2.2/2.2.2.3

) and

is either

/jointfilesconvert/97454/bgp3

/jointfilesconvert/97454/bgp4

(default).

To specify the maximum version, go to a BGP peer prompt
