Scenario: Consider T3 PoPs connected to nearest T2/T1 PoPs via the DS3 or Metro Ethernet Link.
If the reach ability to Network Core is Lost for the T3 PoP, my Customers whose last mile (landing on T3 PoP Router) having Roting Protocol as RIP / BGP / OSPF / EIGRP, the "default-originate" configured at T3 Router is still continuing to originate the default 0.0.0.0 for CE.
Customer's Secondary Link will not Kick-off unless & until the PRY LAST MILE is going DOWN. During this situation, the Customers are impacted & we need to wait until the core reach ability link is restored (or) manually disturb the PRY Customer Link.
In BGP, we are manipulating the case with "BGP Conditional advertisement" using command: "neighbor 10.0.7.6 default-originate route-map"
In RIP / OSPF / EIGRP as the LAST MILE routing protocol for the Customers. How to manipulate this case/situation ?
Request your Help/Support in Advance.
