Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
ip msdp default-peer ip-address | name
[prefix-list list]
Define a default peer from which to accept all MSDP SA messages.
• For ip-address | name, enter the IP address or Domain Name
System (DNS) server name of the MSDP default peer.
• (Optional) For prefix-list list, enter the list name that specifies the
peer to be the default peer only for the listed prefixes. You can have
multiple active default peers when you have a prefix list associated
with each.
When you enter multiple ip msdp default-peer commands with the
prefix-list keyword, you use all the default peers at the same time
for different RP prefixes. This syntax is typically used in a service
provider cloud that connects stub site clouds.
When you enter multiple ip msdp default-peer commands without
the prefix-list keyword, a single active peer accepts all SA
messages. If that peer fails, the next configured default peer accepts
all SA messages. This syntax is typically used at a stub site.
