Configuring Optional Multicast Routing Features
Enabling sdr Listener Support
By default, the switch does not listen to session directory advertisements.
Beginning in privileged EXEC mode, follow these steps to enable the switch to join the default session
directory group (224.2.127.254) on the interface and listen to session directory advertisements. This
procedure is optional.
Command
Step 1
configure terminal
Step 2
interface interface-id
Step 3
ip sdr listen
Step 4
end
Step 5
show running-config
Step 6
copy running-config startup-config
To disable sdr support, use the no ip sdr listen interface configuration command.
Limiting How Long an sdr Cache Entry Exists
By default, entries are never deleted from the sdr cache. You can limit how long the entry remains active
so that if a source stops advertising SAP information, old advertisements are not needlessly kept.
Beginning in privileged EXEC mode, follow these steps to limit how long an sdr cache entry stays active
in the cache. This procedure is optional.
Command
Step 1
configure terminal
Step 2
ip sdr cache-timeout minutes
Step 3
end
Step 4
show running-config
Step 5
copy running-config startup-config
To return to the default setting, use the no ip sdr cache-timeout global configuration command. To
delete the entire cache, use the clear ip sdr privileged EXEC command.
To display the session directory cache, use the show ip sdr privileged EXEC command.
Configuring an IP Multicast Boundary
Administratively-scoped boundaries can be used to limit the forwarding of multicast traffic outside of a
domain or subdomain. This approach uses a special range of multicast addresses, called
administratively-scoped addresses, as the boundary mechanism. If you configure an
