Configure a Route Map

You can configure a route map to filter and update routes. The route map can be associated with a BGP peer and can be used to filter routes based on criteria.
You can optionally configure a route map to filter and update routes. Associate the route map with a BGP peer to filter routes. You can configure multiple route maps but you can apply only one route map to a peer. If filtering needs are identical, you can use the same route map for inbound and outbound traffic.
The branch ION device filters received routes based on the route map. Filters may be based on a prefix list, AS path list, or community list. For example, a peer may advertise 1000 routes, but you may be interested in only 20 routes from this peer. You can apply conditions to filter the 20 routes of interest to the ION device.
Route maps are auto-generated for core and edge peers. You need to create route maps for a classic peer in a branch or a data center. Using match and set criteria and permit and deny clauses, the ION device accepts or denies routes that are advertised.
  1. Select
    Claimed Devices
    Configure the device
    Route Maps
  2. Select
    Create Route Map
    to create a new route map.
  3. On the
    screen, enter a name and optionally enter a description and tags for the route map.
  4. (Optional)
    On the
    screen, click
    Add an Entry
    to add entries to a route map.
    You must create two route map entries using the continue option to filter IPv4 and IPv6 routes for the same peer, as we support a single route map per peer.
    You can either configure IPv4 or IPv6 prefix, not both.
    1. Enter an order number from 1 to 65535 to define the
      in which this route map will be used.
    2. Select
      to allow routes to be advertised or
      to block the routes from being advertised.
    3. (Optional)
      to use the rule that the route matches.
      For example, if a route matches order #10, go to the rule with order #10.
    4. (Optional)
      , choose from the
      Prefix List
      IP Community List
      AS Path List
      , or
      IP Next Hop
      If you have a match criteria for a route map with a set IP-next-hop peer address that needs to be present for both IPv4 and IPv6 prefixes, you must add one more entry with a continue option, and IP-next-hop set as the IPv6 peer address for IPv6 filtering to work.
    5. (Optional)
      , enter values for
      AS Path Prepend
      Local Preference
      , and
      Additive Community
      Where you want to create a customized or autogenerated route map with a set clause as peer-address, you must set peer-address and ipv6-peer-address(with continue entry for both) based on the address-family.
    6. (Optional)
      IP Next Hop
      , select peer-address
      , or IPv6-peer-address,
      or enter an IPv4
      or IPv6
      address of the next hop.
  5. Click
    to create the route map.


Route redistribution is the process of making learned routes from one routing protocol (or a static or connected route) available to a different routing protocol, thereby increasing the accessibility of network traffic. Without route redistribution, a router or virtual router advertises and shares routes only with other routers that run the same routing protocol. You can redistribute IPv4 BGP, connected, or static routes into the OSPF and redistribute OSPF, connected, or static routes into the BGP.
