Border Gateway Protocol (BGPv4)
– 920 –
distance bgp Sets the administrative distance for BGP external, internal,
and local routes
RC
Neighbor Configuration
neighbor activate Enables exchange of routing information with a
neighboring router or peer group
RC
neighbor advertisement-
interval
Configures the interval between sending update messages
to a neighbor
RC
neighbor allowas-in Configures the number of times the AS path for a received
route can contain the same AS number
RC
neighbor attribute-
unchanged
Configures certain attributes to be kept unchanged for
transparent transmission to the specified neighbor
RC
neighbor capability
dynamic
Configures dynamic negotiation of capabilities between
neighboring routers
RC
neighbor capability orf
prefix-list
Configures negotiation of outbound route filter
capabilities with neighboring router
RC
neighbor default-originate Allows the local router to send a default route to a neighbor RC
neighbor description Configures the description of a neighbor or peer group RC
neighbor distribute-list Filters route updates to/from a neighbor or peer group RC
neighbor dont-capability-
negotiate
Disables capability negotiation when creating connections RC
neighbor ebgp-multihop Allows eBGP neighbors to exist in different segments, and
configures the maximum hop count (TTL)
RC
neighbor enforce-multihop Enforces the requirement for all neighbors to form multi-
hop connections
RC
neighbor filter-list Filters route updates sent to or received from a neighbor
based on an AS path access-list
RC
neighbor interface Specifies the interface to a neighbor RC
neighbor maximum-prefix Sets the maximum number or route prefixes that can be
received from a neighbor
RC
neighbor next-hop-self Configures the local router as the next hop for a neighbor RC
neighbor override-
capability
Overrides the result of capability negotiations, allowing a
session to be formed with a peer that does not support
capability negotiation
RC
neighbor passive Passively forms a connection with the specified neighbor,
not sending a TCP connection request, but waiting a
request from the specified neighbor
RC
neighbor password Enables MD5 authentication and sets the key for a
neighboring router
RC
neighbor peer-group
(Creating)
Configures a router peer group which can be easily
configured with the same attributes
RC
neighbor peer-group
(Group Members)
Assigns routers to a peer group RC
neighbor port Specifies the TCP port number of the partner through
which communications are carried
