Clarifications and Known Behaviors
ExtremeWare 7.1.1 Release Notes 49
RIP in Conjunction with other Routing Protocols
It is recommended that RIP be enabled only on routers running with less than 10,000 routes from other
routing protocols, such as BGP or OSPF.
OSPF
AS-external LSAs Might Not Be Regenerated
AS-external LSAs are not regenerated after an active LSA is removed or a neighbor goes down
(PD2-149426154).
Do Not Enable originate-router-id when Router ID
Do not enable the OSPF originate-router-id feature when a loopback with the OSPF router ID is
configured (PD2-151536301).
Error Message Not Generated
If you configure a low ase-limit with a lot of type-5 LSAs, enabling OSPF causes a database overflow
state before OSPF adjacency is built. This should generate a critical error message, but does not
(PD2-148164866).
Routes not Installed with Duplicate LSAs
When there are duplicate LSAs in the LSDB from different advertising switches, the route might not be
installed in the kernel routing table. To work around this, disable and enable OSPF (PD2-132370484).
Disable OSPF Before Adding or Removing External Area Filters
If you configure an OSPF area external filter on an ABR, and the filter is set to exclude routes that have
already been learned, an OSPF failure occurs. A workaround is to disable OSPF before adding or
removing OSPF external area filters (PD2-105170634).
IS-IS
Unicast Packets Considered Broadcast
Unicast packets are occasionally considered broadcast packets and dropped (PD2-142499344).
BGP
Large Number of Access Profiles and a Peer Reset
You can add a maximum of 10 BGP community numbers in inbound and/or outbound route updates
using access-profiles and/or route-maps. If you add more communities, BGP might crash
(PD2-160136950).
