Summary

RFC 1771 -> RFC 4271

Standards and Technologies:

  • RFC 4271 Border Gateway Protocol 4
  • RFC 4456 BGP Route Reflection
  • RFC 1965 Autonomous System Confederations for BGP
  • RFC 1997 BGP Communities Attribute
  • RFC 2385 TCP MD5 Authentication for BGPv4
  • RFC 3392 Capabilities Advertisement with BGP-4
  • RFC 2918 Route Refresh Capability
  • RFC 2858 Multiprotocol Extensions for BGP-4
  • RFC 2545 Use of BGP-4 Multiprotocol Extensions for IPv6 Inter-Domain Routing


Instance

Sub-menu: /routing bgp instance


as (integer: 0..65535; Default: ) - BGP autonomous system number

client-to-client-reflection (yes | no; Default: yes) - in case this instance is a route reflector: whether to redistribute routes learned from one routing reflection client to other clients

cluster-id (IP address; Default: ) - in case this instance is a route reflector: cluster ID of the router reflector cluster this instance belongs to. This attribute helps to recognize routing updates that comes from another route reflector in this cluster and avoid routing information looping. Note that normally there is only one route reflector in a cluster; this case 'cluster-id' does not need to be configured and BGP router ID is used instead

confederation (integer: 0..65535; Default: ) - in case of BGP confederations: autonomous system number that identifies the [local] confederation as a whole

confederation-peers (integer: 0..65535; Default: ) - in case of BGP confederations: list of BGP peers internal to the [local] confederation

ignore-as-path-len (yes | no; Default: no) - whether to ignore AS_PATH attribute in BGP route selection algorithm

name (string; Default: "") - BGP instance name

out-filter (string; Default: "") - the output routing filter used by all BGP peers belonging to this instance

redistribute-connected (yes | no; Default: no) - if enabled, this BGP instance will redistribute the information about connected routes, i.e., routes to the networks that can be directly reached

redistribute-ospf (yes | no; Default: no) - if enabled, this BGP instance will redistribute the information about routes learned by OSPF

redistribute-other-bgp (yes | no; Default: no) - if enabled, this BGP instance will redistribute the information about routes learned by other BGP instances

redistribute-rip (yes | no; Default: no) - if enabled, this BGP instance will redistribute the information about routes learned by RIP

redistribute-static (yes | no; Default: no) - if enabled, the router will redistribute the information about static routes added to its routing database, i.e., routes that have been created using the '/ip route add' command on the router

router-id (IP address; Default: 0.0.0.0) - the BGP Router ID (for this instance). If not specified, BGP will use one of router's IP addresses.
