FAQ: What Two Components Used To Identify A Neighbor In A Bgp Configuration?

Which two components are used to identify a neighbor in a BGP?

Which two components are used to identify a neighbor in a BGP configuration? (Choose two.) Explanation: Use the show ip bgp neighbors (registered customers only) command to display information about the TCP and Border Gateway Protocol (BGP) connections and verify if the BGP peer is established.

What is BGP neighbor activate?

If a neighbor is activated, BGP also sends the full contents of the BGP routing table of the newly activated address family.

How do I establish a BGP neighbor?

To configure the BGP peer sessions:

  1. Configure the interfaces to Peers A, B, C, and D.
  2. Set the autonomous system (AS) number.
  3. Create the BGP group, and add the external neighbor addresses.
  4. Specify the autonomous system (AS) number of the external AS.
  5. Add Peer D, and set the AS number at the individual neighbor level.

How do I remove BGP neighbor?

To specify that a community’s attribute should be sent to a BGP neighbor, use the neighbor send-community command in address family or router configuration mode. To remove the entry, use the no form of this command.

What are different BGP message types?

How do I find my best path in BGP?

  1. Prefer the highest local-preference value.
  2. Prefer the shortest AS-path length.
  3. Prefer the lowest origin value.
  4. Prefer the lowest MED value.
  5. Prefer routes learned from an EBGP peer over an IBGP peer.
  6. Prefer best exit from AS.
  7. For EBGP-received routes, prefer the current active route.

Why OSPF route is preferred over BGP?

Scale: BGP is more flexible and scalable than OSPF and it is also used on a larger network. Preferred path: OSPF is used to determine the fastest route while BGP puts emphasis on determining the best path.

What are the stages of BGP?

Here they are:

  • Idle:This is the first state where BGP waits for a “start event”.
  • Connect: BGP is waiting for the TCP three-way handshake to complete.
  • Active: BGP will try another TCP three-way handshake to establish a connection with the remote BGP neighbor.

What is BGP FSM?

BGP forms a TCP session with neighbor routers called peers. BGP uses the Finite State Machine (FSM) to maintain a table of all BGP peers and their operational status. The BGP session may report in the following states: Idle.

Can I run two BGP process on single router?

You can use multiple instances of BGP to maintain separate per-site forwarding tables for keeping VPN traffic separate on the PE router.
