Ibgp administrative distance

config-bgp-ipv4-uc. config-bgp-ipv6-uc 2017-02-07 Cisco documentation describes "administrative distance" as "This is the measure of trustworthiness of the source of the route. If a router learns about a destination from more than one routing protocol, administrative distance is compared and the preference is given to the routes with lower administrative distance. This presents problems because the metrics, attributes, and administrative distances of each routing protocol are different.

RTA received routes from iBGP and OSPF but the issue ospf win over iBGP. In this case we want to route traffic towar 2017-06-02 Known via "bgp 65531", distance 20, metric 0 Tag 65535, type external Last update from 00:18:12 ago Routing Descriptor Blocks: *, from, 00:18:12 ago Route metric is 0, traffic share count is 1 AS Hops 2 Route tag 65535 MPLS label: none . And now we have completed all the steps to configure iBGP in Cisco Each routing protocol has its own Administrative Distance (AD), which is a value representing the trustworthiness of the specific routing protocol.
