Description
periodically check whether there is a route to reach the next hop in the
routing table.
Enter the keep-alive interval value here. This is used to send keep-
alive messages to BGP peers. The range is from 0 to 65535 seconds.
By default, this value is 60 seconds.
Enter the hold-time value here. This is the length of the timeout value
of the keep-alive message. The software will declare a BGP peer dead
after the timeout. The range is from 0 to 65535 seconds. By default,
this value is 180 seconds.
Select to enable or disable the always compare Multi Exit Discriminator
(MED) feature here. This feature is used to configure the MED in best
path selection for paths that are advertised from neighbors in either the
same or different autonomous systems.
Select to enable or disable the deterministics MED feature here. This
feature is used to include the MED value between all paths received
from within the same autonomous system in the selection of the best
route selection.
Enter the default local preference value here to apply to the routes
received by this router. The range of is from 0 to 4294967295. By
default, this value is 100. The local preference number is used to
control the preferred exit point from the local AS to the same
destination network. The local preference will be sent with the route
advertised to the iBGP peers. If an external route is both reachable via
the local router and an iBGP peer router, the local preference value
determines the preferred exit point to reach the external route.
Select to enable or disable the MED confederation feature here. This
feature is used to configure a BGP routing process to compare the
MED between paths learned from confederation peers.
Select to enable or disable the AS path ignore feature here. This
feature is used to ignore the AS path as a discriminating factor in
selection of the best path.
Select to enable or disable the compare router ID feature here. This
feature is used to compare the router ID when comparing paths that
have identical comparing factors.
Select to enable or disable the MED missing AS worst feature here.
This feature is used to configure the router to assign a infinite value to
the route if it is missing an MED.
Select to enable or disable the compare confederation path feature
here. This feature is used to configure a BGP routing process to
compare the confederation AS path length of the routes received.
Select to enable or disable the fast external fail-over feature here. This
feature is used to immediately reset an external BGP peering session
if the link directly connected to the peer goes down.
Select to enable or disable the aggregate next hop check feature here.
This feature is used to enable the checking of the next hop of the BGP
aggregated routes. Only the routes with the same next hop attribute
can be aggregated if the BGP aggregate next hop check is enabled.
Select to enable or disable the default IPv4 unicast feature here. This
feature is used to enable the exchange of IPv4 unicast routing
information.
Select to enable or disable the graceful restart state here. This feature
is used to enable the BGP graceful restart capabilities for all BGP
