How do I advertise a default route in BGP?
To advertise a BGP default route to a BGP neighbor, use the neighbor default-originate router configuration command. For example, when the IP prefix 0.0. 0.0/0 is removed from the BGP table with the no network command and the default route advertisement is configured on EBGP session from PE-A to Site-A …
How do I propagate a default route in EIGRP?
One way to inject a default route into EIGRP is to configure a static default route pointing to Null0 and then redistribute the default route into EIGRP. When redistributing a static, connected, or EIGRP route for another AS, the metric does not need to be assigned. The default route will be an external EIGRP route.
What is redistribute in BGP?
When we run BGP together with any IGP routing, sometimes it is required to redistribute BGP routes into that IGP. This usually required where BGP peers are separated by certain number of hops that aren’t participating in BGP — so they don’t know the route to the destination network that is advertised by BGP.
What is default originate in BGP?
“default-information originate causes the default route to be artificially generated and injected into the BGP RIB, regardlessly of whether it is present in the routing table.”
How can default route be generated?
Default routes can also be generated by dynamic routing protocols, such as OSPF and IS-IS. Default routes are used only when no matching routing entry is available for packet forwarding in the routing table. A default route in the routing table is the route to the network 0.0.
What is Eigrp metric?
EIGRP determines the value of the path using five metrics: bandwidth, load, delay, reliability and MTU. EIGRP uses Five different messages to communicate with its neighbor routers. EIGRP messages are Hello, Update, Query, Reply, and Acknowledgement.
Can we redistribute BGP in IGP Please explain your answers?
As mentioned, redistributing internal BGP (iBGP) into any IGP is disabled by default and it can be overridden using this command, but it is never recommended. iBGP administrative distance (AD) is higher than the AD of any IGP, so redistributed routes will always be preferred via the IGP.
Can you redistribute RIP into BGP?
Configures the device to redistribute connected routes, learned static routes, OSPF routes, or BGP4 routes through RIP. The RIP router can then advertise these routes to RIP neighbors.
