Layer 3 Routing Commands 1364
IPv4 Unicast Support Indicates whether IPv4 unicast routes can be exchanged
with this peer. Both indicates that IPv4 is active locally
and the neighbor indicated support for IPv4 unicast in
its OPEN message. Sent indicates that IPv4 unicast is
active locally, but the neighbor did not include this
AFI/SAFI pair in its OPEN message. IPv4 unicast is
always enabled locally and cannot be disabled.
IPv6 Unicast Support Indicates whether IPv6 unicast routes can be exchanged
with this peer. Both and Sent have the same meaning as
for IPv4. None indicates that neither the local router
nor the peer has IPv6 enabled for this adjacency.
Received indicates that the peer advertised the IPv6
unicast capability, but it is not enabled locally. IPv6
unicast is enabled locally using the neighbor activate
command in address-family IPv6 configuration mode.
RFC 5549 Support Shown if support for RFC 5549 is enabled and the BGP
neighbor is peered over IPv6 network.
Update Source The configured value for the source IP address of
packets sent to this peer. This field is only included in
the output if the update source is configured.
Local Interface Address The IPv6 address used as the source IP address in
packets sent to this neighbor.
Configured Hold Time The time, in seconds, that this router proposes to this
neighbor as the hold time
Configured Keep Alive
Time
The configured KEEPALIVE interval for this neighbor.
Negotiated Hold Time The minimum configured hold time and the hold time
in the OPEN message received from this neighbor. If the
local router does not receive a KEEPALIVE or UPDATE
message from this neighbor within this interval of time,
the local router drops the adjacency. This field is only
shown if the adjacency state is OPEN CONFIRM or
greater.
Keep Alive Time The number of seconds between KEEPALIVE messages
sent to this neighbor. This field is only shown if the
adjacency state is OPEN CONFIRM or greater.
