Web3 feb. 2015 · To understand why, and to understand the Calico answer to both of those questions, we need to look a bit at how BGP and IGPs are used in large–scale networks today. Where (and why) are certain protocols used in a large network. Any network, but especially a large network has two different routing issues it needs to deal with: WebIn a “third party next hop” network, that is, a BGP router has two eBGP peers in a common broadcast subnet, the BGP router does not specify itself as the next hop for routes sent to such an eBGP peer, unless the neighbor next-hop-self command is configured. BGP checks if the AS_PATH attribute of a route from a peer contains the local AS number. WebThe first value 10.100.9.9 is the next hop for the BGP route. The second value 10.100.17.17 is the IP-address you mentioned in the neighbor command under the BGP process. The third value 10.100.17.17 in brackets is the router-id of the BGP speaker that advertised the route. This value can be the same or different than the second value. green lake county clerk of circuit court
