Workaround
The communication can be restored either by disconnecting and then reconnecting the handset
end of the serial cable, or by power-cycling the handset.

When the antenna of the Siemens M35 modem connected to the serial interface of the
Cisco 3200 router is detached, the Cisco 3200 router will maintain PPP connection although IP
traffic cannot be send or received.

CSCeb06521—Two mobile tunnels may be created pointing to different home agents.
When the Priority HA feature is configured and connectivity to registered HA is lost, a
CCoA-registered mobile router may not delete its Mobile IP tunnel to that HA after that HA
registration is deleted. This may cause problems for traffic passing though the mobile router when
it subsequently registers with another HA.

Workaround
None.

CSCeb06827—Europe Vodafone wireless does not work on Mobile IP.
Vodafone uses Network Address Translation (NAT)/Port Address Translation (PAT) in its network,
which causes problems for Mobile IP, because Mobile IP uses either generic routing encapsulation
(GRE) or IP encapsulation that lacks a port to translate.

CSCdu53656
A Cisco device running IOS and enabled for the Border Gateway Protocol (BGP) is vulnerable to a
Denial of Service (DOS) attack from a malformed BGP packet. The BGP protocol is not enabled by
default, and must be configured in order to accept traffic from an explicitly defined peer. Unless the
malicious traffic appears to be sourced from a configured, trusted peer, it would be difficult to inject
a malformed packet. BGP MD5 is a valid workaround for this problem.
