I have the next problem . I have a lot of routers with MPLS , bgp and Router Reflectors .
Every site have redundancy , by two PEs and two distribution Switches .
In the case when I using redistribution between EIGRP and BGP , I am filtering the routers from the PE at side with filters in Route Rflectors . I am using "EIGRP SOO" for updates from EIGRP passing to BGP .
The loop is appearing when the routes are coming from another AS BGP . In this case , the loops is formed because the route is advertised to another routers ,is redistributed from BGP to EIGRP and this route is returned to BGP .
The only way to stop this routes is by distribute-list in EIGRP , but this solution is not scalable .
How can I made these ???
Is possible to mark the routes advertised from another AS , publish to anothers PEs and stop this adertising withou using distribute-list in the distribution routers ?
