Configuration Guide 11. Dynamic IP Routing
11.4.2 Filtering Dynamic Routing Protocol Routes
You can manipulate the BGP/OSPF/RIP routing advertisements using the route-map
menu. Route-map contains tools to prioritize routes from specific BGP/OSPF/RIP sources,
as well as denying some BGP/OSPF/RIP sources to be advertised in the MSBR routing
table. The example below demonstrates both methods:
