WebOct 14, 2006 · BGP can run in two modes that each has a very different behavior when advertising routing information. EBGP: external BGP runs between routers in different ASs. IBGP: internal BGP runs between routers in the same AS. EBGP: routes received from an EBGP peer can be advertised to EBGP and IBGP peers. WebEBGP has been configured between R1/R2 and also between R4/R5. IBGP is configured between R2/R4 and R3 on top doesn’t run BGP at all. The routers within AS2 are configured with OSPF, this is required since R2/R4 have to be able to reach each other to establish the IBGP session.

WebWhy IGP protocols like EIGRP, RIP and OSPF uses Multicast Hello Packetsto find the Neighbors where as BGP does not use any multicast packets for neighbor discovery. 2.

WebJun 22, 2024 · The IGP metric to the BGP next hop must be equal to the best-path IGP metric. These are the additional requirements for iBGP multipath: The path must be learned from an internal neighbor (iBGP). The IGP metric to the BGP next hop must be equal to the best-path IGP metric, unless the router is configured for unequal-cost iBGP multipath. WebThe main thing you have to understand is that EBGP forms adjacencies between AS boundaries, IBGP is used within an AS. IBGP requires either a full-mesh, or route reflectors. This is because the AS-path attribute is not updated across an IBGP adjacency, which could otherwise cause routing loops.

WebDec 4, 2024 · Similar to link state protocols, EIGRP does form neighbor adjacencies and sends event-triggered updates instead of periodic full routing table updates. BGP is a path vector protocol that advertises the destination path comprised of single of multiple autonomous system numbers (ASN) with each route.
