undo import-source
View
Public network MSDP view, VPN instance MSDP view
Default level
2: System level
Parameters
acl-number: Specifies a basic or advanced ACL number, in the range of 2000 to 3999. A basic ACL
filters multicast sources, and an advanced ACL filters multicast sources or multicast groups. If you do not
provide this argument in your command, no multicast source information is advertised.
Description
Use import-source to configure a rule of creating (S, G) entries.
Use undo import-source to remove any rule of creating (S, G) entries.
By default, when an SA message is created, no restrictions are defined for the (S, G) entries to be
advertised in it. Namely, all the (S, G) entries within the domain are advertised in the SA message.
During ACL matching, the protocol ID in the ACL rule is not verified.
In addition to controlling SA message creation by using this command, you can also configure a filtering
rule for forwarding and receiving SA messages by using the peer sa-policy command.
Related commands: peer sa-policy.
Examples
# Configure the MSDP peer on the public network to advertise only the (S, G) entries of multicast sources
on the 10.10.0.0/16 subnet and with a multicast group address of 225.1.0.0/16 when creating an SA
message.
