Resolved Caveats—Cisco IOS Release 12.0(27)S5
Conditions: This symptom is observed only in networks where all of the EIGRP neighbors are
declared as stub.
Workaround: Remove the EIGRP stub feature or clear the IP EIGRP neighbors.

Symptoms: When you configure the distribute-list router configuration command under the
address-family ipv4 vrf vrf name router configuration command, the distribute-list router
configuration command may appear under the main routing process as may be displayed in the
output of the show running-config EXEC command.
Conditions: This symptom is observed in either a Routing Information Protocol version 2 (RIPv2)
or a Border Gateway Protocol (BGP) configuration when you specify the interface-type and
interface-number arguments of the distribute-list {access-list-number | access-list-name} {in |
out} [interface-type interface-number] router configuration command.
The symptom does not occur when you do not define the interface-type and interface-number
arguments and only enter the distribute-list {access-list-number | access-list-name} {in | out}
router configuration command.
Workaround: There is no workaround.

Symptoms: ARP may not function properly on the remote side of point-to-point Fast Ethernet link
with a default static route until the remote side is pinged.
Conditions: This symptom is observed on a Cisco router when ARP and /31 mask are configured on
a point-to-point link Fast Ethernet link with a default static route. The symptom is
platform-independent.
Workaround: There are four different workarounds:
- Use a /30 netmask on the point-to-point Fast Ethernet connection.
- Configure a static ARP entry for the remote side of the Fast Ethernet link.
- Enter the ip proxy-arp command on the remote side of the Fast Ethernet link.
- Use an OSPF route instead of a default static route.

Symptoms: BGP may fail to reestablish a session when you remove a line card, PA, VIP, or module
and replace it with a card of a different type. For example, the problem occurs when you remove a
1-port GE line card and replace it with a 3-port GE line card. However, if you replace the 1-port GE
line card with another 1-port GE line card (or you just plug the same 1-port GE line card back in the
chassis), the problem does not occur.
Conditions: This symptom is observed when the router one side of the BGP session is configured
with the neighbor ip-address transport connection-mode active command and when a line card,
PA, VIP, or module is changed on the router at the other side of the BGP session. Furthermore, the
router at the other side of the BGP session is configured with the neighbor ip-address
update-source interface command, and the interface argument refers to the interface on the line
card, PA, VIP, or module that is changed.
Workaround: Disable and reenter the neighbor ip-address update-source command.

Symptoms: A Cisco router may reload unexpectedly when you enter the show ip msdp peer
command.
