The BGP configuring commands are shown in the table below. These commands are available in the router's configuration mode and context configuration mode (config-router)#.

Table 50

Command Mode Description

router bgp <AS number>

Configuration Switch to the BGP configuration mode address-family ipv4

{unicast | multicast}

Context Switch to the address-family configuration mode aggregate-address

bgp as-local-count <2-64>

Context Specify the number of the own AS in the AS-path attribute

bgp bestpath ... Context Change the best path selecting algorythm bgp client-to-client

reflection

Context Enable the reflector role bgp cluster-id

Context Specify the neighbors in confederation bgp config-type

{standard | ecorouteros}

Context Specify the configuration type, the ecorouteros is enabled by default, to transmit the community attribute the standard type is used

bgp dampening ... Context Configure BGP route dampening parameters bgp default

local-preference <0-4294967295>

Context Specify the local presence attribute

bgp deterministic-med Context Compare the MED attributes for the route recieved from an AS; the AS, weight, local preference, AS-path, and origin must be equal

bgp enforce-first-as Context The update message recieved not from the neighboring configured AS will be discarded

Command Mode Description

bgp fast-external-failover

Context Instant reset of the BGP session when interface failed bgp nexthop-trigger

delay <1-100>

Configuration Specify the delay interval to refresh BGP table after nexthop parameters changed

bgp nexthop-trigger enable

Configuration Enable the neighbor address specific monitoring bgp rfc1771-path-select Configuration Enable the best path selection according to RFC 1771 bgp rfc1771-strict Configuration Specify the origin attribute according to RFC 1771 bgp router-id <адрес> Context Specify router's BGP identifier

bgp scan-time <0-60> Context Specify the route accessibility scanning period in the route table (60 sec by default)

distance bgp <1-255>

<1-255> <1-255>

Context Specify administrative distance for external, internal, local routes

max-paths {ebgp | ibgp} <2-64>

Context Maximum number of equal-cost routes

mpls-resolution Context An automatic creation of the FTN record for prefixes recieved from the neighbors

neighbor <address>

activate

Context Activate neighborhood in address-family configuration mode

neighbor <address>

advertisement-interval

<0-65535>

Context Specify the minimum interval between Update messages

neighbor <адрес>

allowas-in <1-10>

Context Advertise prefixes (routes) even when the source of the prefixes is from the same Autonomous System (AS) number

neighbor <address> as-origination-interval <1-65535>

neighbor <адрес>

capability dynamic

Context Enable the dynamic capability for a specific peer. This command allows a BGP speaker to advertise or

withdraw an address family capability to a peer in a non-disruptive manner.

neighbor <адрес>

capability orf prefix-list

Context Enable Outbound Router Filtering (ORF), and advertise the ORF capability to its neighbors. The ORFs send and receive capabilities to lessen the number of updates exchanged between neighbors. By filtering updates, this option minimizes generating and processing of updates.
