Extension attribute redistribution
Extension attribute redistribution enables routing protocols to learn route extension attributes from
each other, including BGP extended community attributes, OSPF area IDs, route types, and router
IDs.
The RIB records extended attributes of each routing protocol and redistribution relationships of
different routing protocol extended attributes.
Setting the maximum lifetime for routes and labels
in the RIB
Perform this task to prevent routes of a certain protocol from being aged out due to slow protocol
convergence resulting from a large number of route entries or long GR period.
The configuration takes effect at the next protocol or RIB process switchover.
To set the maximum lifetime for routes and labels in the RIB (IPv4):

Setting the maximum lifetime for routes in the FIB
When GR or NSR is disabled, FIB entries must be retained for some time after a protocol process
switchover or RIB process switchover. When GR or NSR is enabled, FIB entries must be removed
immediately after a protocol or RIB process switchover to avoid routing issues. Perform this task to
meet such requirements.
