In the exhibit, BGP is configured withlocal AS 65101and a neighbor at172.16.1.1inpeer AS 65201. This setup involves two different Autonomous Systems (AS), indicating anExternal BGP (EBGP)configuration.
Step-by-Step Breakdown:
* EBGP vs. IBGP:
* EBGPis used between routers in different ASes. In this case, the local AS is65101and the peer AS is65201, meaning the BGP session isEBGP.
* IBGPis used between routers within the same AS, which is not applicable here as the AS numbers are different.
* BGP Group Configuration:
* The configuration does not require a type external parameter because Junos OSautomatically recognizes the session asEBGPwhen the local and peer AS numbers are different.
* The BGP session will operate as EBGP, and the configuration will commit successfully.
Juniper Reference:
* BGP Configuration: In Juniper, EBGP is automatically recognized when the local and peer AS numbers differ, without needing to specify type external.
