Symptoms: A network and host-based configuration download over serial HDLC with an IP address
obtained via SLARP fails.

Conditions: This symptom has been observed with a router that has no startup- configuration (after
using the write erase command) but is staged for autoinstall over a serial link. An IP address is
obtained, but the download fails with the following error message:

Workaround: Use another method of autoinstall if possible, or pre- configure the router before
deployment.

Symptoms: A candidate Cisco Bootstrap Router (BSR) that is configured for PIM version 2 and that
is elected as a BSR does not change back to a candidate BSR immediately after the BSR interface
is shut down but waits until the timer expires. This situation prevents another candidate BSR from
becoming a BSR until the first BSR changes back to a candidate BSR when the timer expires.

Symptoms: When you enter the ip pim vrf register-source command on an interface and then delete
the interface or its IP address, the command remains in the configuration. This situation causes the
bulk synchronization to fail and the standby RP to reset continuously after an RP switchover has
occurred. Then, because the register source (the interface) cannot be found, a BEM failure occurs.

VRF and when the interface has a register source configured.
