BGP peer groups are used to simplify configuration and to improve performance. It can be used when a router has a group of neighbors with the same update policies. The update is generated once per group rather than for each neighbor.
For BGP, a neighbor relationship to be established, source IP address of BGP packets sent by a router must be the same as neighbor ip-address set on the neighboring router. By default, packet’s source IP address is outgoing interface.
Hi everybody! This is first lab from BGP series and here I would like to talk about basic bgp configuration. If you are new to bgp you need to know that each BGP router belong only to one Autonomous System (AS)
