Enabling Message Digest 5 Authentication Between Peers
You can enable Message Digest 5 (MD5) authentication between two BGP peers,
causing each segment sent on the TCP connection between them to be verified. You
must configure the same password on both BGP peers; otherwise, the connection
between them is not made. The authentication feature uses the MD5 algorithm
command that causes the generation and checking of the MD5 digest on every
segment sent on the TCP connection. Configuring a password for a neighbor
terminates an existing session and establishes a new one. If you specify a BGP peer
group using the
name
argument, all the members of the peer group inherit the
characteristic configured with this command.
Use the neighbor password command in Router Configuration mode to enable MD5
authentication:
MOT(config-bgp)#
neighbor {<
A.B.C.D
> | <
WORD
>} password <
string
>
where:
A.B.C.D
is the IP address of the BGP-speaking neighbor.
WORD
is the name of the BGP peer group.
string
is a case-sensitive password of up to 32 ASCII characters.
Example
The commands in the following example enable the authentication feature between a
router and the BGP neighbor at 122.35.3.1. The password that must also be
configured for the neighbor is
mypassword.
MOT(config)#router bgp 109
MOT(config-bgp)#neighbor 122.35.3.1 password mypassword
Setting the Routing Updates Interval
Use the neighbor advertisement-interval command in Router Configuration mode
to set the minimum interval between the sending of BGP routing updates to neighbors
or peer groups. Lower values for the advertisement interval cause route changes to be
reported more quickly. However, use caution because this action may cause the
routers to use more bandwidth.
MOT(config-bgp)#
neighbor {<
A.B.C.D
> | <
WORD
>} advertisement-interval
<
0-600
>
where:
A.B.C.D
is the IP address of the neighbor.
