Multicast Source Discovery Protocol (MSDP) Configuration
========================================================
.. clicmd:: ip msdp mesh-group [WORD] member A.B.C.D
MSDP can be setup in different ways:
Include a MSDP peer as a member of a MSDP mesh-group.
* MSDP meshed-group: where all peers are connected with each other creating
a fully meshed network. SAs (source active) messages are not forwarded in
this mode because the origin is able to send SAs to all members.
.. clicmd:: ip msdp mesh-group [WORD] source A.B.C.D
This setup is commonly used with anycast.
Create a MSDP mesh-group, defining a name for it and an associated local source
address.
* MSDP peering: when there is one or more peers that are not fully meshed. SAs
may be forwarded depending on the result of filtering and RPF checks.
This setup is commonly consistent with BGP peerings (for RPF checks).
* MSDP default peer: there is only one peer and all SAs will be forwarded
there.
.. note::
MSDP default peer and SA filtering is not implemented.
Commands available for MSDP:
.. clicmd:: ip msdp mesh-group WORD member A.B.C.D
Create or update a mesh group to include the specified MSDP peer.
.. clicmd:: ip msdp mesh-group WORD source A.B.C.D
Create or update a mesh group to set the source address used to connect to
peers.
.. clicmd:: ip msdp peer A.B.C.D source A.B.C.D
Establish a MSDP connection with a peer.
Create a regular MSDP session with peer using the specified source address.
Remove a MSDP peer member from a MSDP mesh-group.
Delete a MSDP mesh-group.
Delete a MSDP peer connection.
