This command configures a TCP RSA Data Security, Inc. MD5 Message-Digest Algorithm password for an MSDP peer.This command enables TCP RSA Data Security, Inc. MD5 Message-Digest Algorithm authentication for a MSDP peer. When a password is configured, MSDP receives only authenticated MSDP messages from its peers. All MSDP messages that fail TCP RSA Data Security, Inc. MD5 Message-Digest Algorithm authentication are dropped.
| peer all | Specifies all MSDP peers. |
| remoteaddr | Specifies the IP address of the MSDP peer. |
| none | Removes the previously configured password. |
| encrypted | Encrypts the password for RSA Data Security, Inc. MD5 Message-Digest Algorithm authentication. To improve security, the password displays in encrypted format and cannot be seen as simple text. Additionally, the password is saved in encrypted format. |
| tcpPassword | Specifies the password to use for RSA Data Security, Inc. MD5 Message-Digest Algorithm authentication at the TCP level. The password must be an ASCII string with a maximum of 31 characters. |
| vrname | Specifies the name of the virtual router to which this command applies. If a name is not specified, it is extracted from the current CLI context. |
By default, TCP RSA Data Security, Inc. MD5 Message-Digest Algorithm authentication is disabled for the MSDP peer.
We recommend that you enable TCP RSA Data Security, Inc. MD5 Message-Digest Algorithm authentication for all MSDP peers to protect MSDP sessions from attacks. You can execute this command only when the MSDP peer is disabled or when MSDP is globally disabled on that VR.
The following example configures a password for the MSDP peer with the IP address 192.168.45.43, which automatically enables TCP MD5 authentication:
configure msdp peer 192.168.45.43 password test123
The following command removes the password:
configure msdp peer 192.168.45.43 password none
