Symptoms: Bidirectional Forwarding Detection (BFD) sessions do not scale. This symptom is
especially visible with an OSPF client when one of the peers is rebooted after configuring the
maximum number of BFD sessions.
Conditions: This symptom occurs when configuring maximum BFD sessions or total number of
BFD sessions too close to the maximum limit.
Workaround: Configure 90 percent of the maximum allowed BFD sessions.

Symptoms: Large packets may be dropped when running Bridge Control Protocol (BCP).
Conditions: When BCP is under test, sweep ping fails when large tagged package is sent across the
routers with BCP configured on serial ports. Specifically, for datagram sizes in the range [Min
size=36, 1406] inclusive, ping goes through. But for larger datagrams in the range [1490
18024=Max Size] inclusive, the ping across the bridge fails.
Workaround: There is no workaround.

Symptoms: Class-Based Tunnel Selection (CBTS) member tunnels are not recovered while
performing an SSO operation.
Conditions: Occurs when CBTS is configured and a SSO is triggered The member tunnels are
resignalled after the SSO recovery period, but this problem results in traffic loss while the recovery
is in progress.
Workaround: There is no workaround.

Symptoms: A Cisco 7600 series router that is running Cisco IOS Release 12.2(33) SRB2 does not
report all the Netflow flows even though ip flow ingress is configured. This happens when the box
comes up after reload. Also very few flows are exported to the collector.
Conditions: This symptom occurs under the following conditions:
- Interface NDE is configured in the box
- After the 7600 has come up after the reload.
- Box has to have SIP-400 LCs.
Workaround: Configure ip route-cache flow on the main interface or configure no ip flow ingress
followed by ip flow ingress on the sub-interface.

Symptom: OIF are not correctly programmed.
Conditions: The replication mode is egress. Multicast flows are injected from multiple ports and
joins are received from the ports.
