6.1 MSDP Configuration Commands
6.1.1 cache-sa-enable
Syntax
cache-sa-enable
undo cache-sa-enable
View
MSDP view
Parameter
None
Description
Use the cache-sa-enable command to enable the router to cache SA state.
Use the undo cache-sa-enable command to remove the cache from the router.
By default, the router caches the SA state, i.e., (S, G) entry after it receives SA
messages.
If the router is in cache state, it will not send SA request message to the specified
MSDP peer when it receives a new group join message.
Example
# Configure the router to cache all the SA states.
<Quidway> system-view
System View: return to User View with Ctrl+Z.
