Configure Route Redistribution

Perform the following procedure to configure route redistribution.
  1. Create a redistribution profile.
    1. Select
      Network
      Virtual Routers
      and select a virtual router.
    2. Select
      Redistribution Profile
      and
      IPv4
      or
      IPv6
      and
      Add
      a profile.
    3. Enter a
      Name
      for the profile, which must start with an alphanumeric character and can contain zero or more underscores (_), hyphens (-), dots (.), or spaces (up to 16 characters).
    4. Enter a
      Priority
      for the profile in the range 1 to 255. The firewall matches routes to profiles in order using the profile with the highest priority (lowest priority value) first. Higher priority rules take precedence over lower priority rules.
    5. For
      Redistribute
      , select one of the following:
      • Redist
        —Select for redistribution the routes that match this filter.
      • No Redist
        —Select for redistribution routes that match the redistribution profiles except the routes that match this filter. This selection treats the profile as a block list that specifies which routes not to select for redistribution. For example, if you have multiple redistribution profiles for BGP, you can create a
        No Redist
        profile to exclude several prefixes, and then a general redistribution profile with a lower priority (higher priority value) after it. The two profiles combine and the higher priority profile takes precedence. You can’t have only
        No Redist
        profiles; you would always need at least one
        Redist
        profile to redistribute routes.
    6. On the
      General Filter
      tab, for Source Type, select one or more types of route to redistribute:
      • bgp
        —Redistribute BGP routes that match the profile.
      • connect
        —Redistribute connected routes that match the profile.
      • ospf
        (
        IPv4 only
        )—Redistribute OSPF routes that match the profile.
      • rip
        (
        IPv4 only
        )—Redistribute RIP routes that match the profile.
      • ospfv3
        (
        IPv6 only
        )—Redistribute OSPFv3 routes that match the profile.
      • static
        —Redistribute static routes that match the profile.
    7. (
      Optional
      ) For
      Interface
      ,
      Add
      one or more egress interfaces of associated routes to match for redistribution. To remove an entry, click
      Delete
      .
    8. (
      Optional
      ) For
      Destination
      ,
      Add
      one or more IPv4 or IPv6 destinations of routes to match for redistribution. To remove an entry, click
      Delete
      .
    9. (
      Optional
      ) For
      Next Hop
      ,
      Add
      one or more next hop IPv4 or IPv6 addresses of routes to match for redistribution. To remove an entry, click
      Delete
      .
    10. Click
      OK
      .
  2. (
    Optional—When General Filter includes ospf or ospfv3
    ) Create an OSPF filter to further specify which OSPF or OSPFv3 routes to redistribute.
    1. Select
      Network
      Virtual Routers
      and select the virtual router.
    2. Select
      Redistribution Profile
      and
      IPv4
      or
      IPv6
      and select the profile you created.
    3. Select
      OSPF Filter
      .
    4. For Path Type, select one or more of the following types of OSPF path to redistribute:
      ext-1
      ,
      ext-2
      ,
      inter-area
      , or
      intra-area
      .
    5. To specify an
      Area
      from which to redistribute OSPF or OSPFv3 routes,
      Add
      an area in IP address format.
    6. To specify a
      Tag
      ,
      Add
      a tag in IP address format.
    7. Click
      OK
      .
  3. (
    Optional—When General Filter includes bgp
    ) Create a BGP filter to further specify which BGP routes to redistribute.
    1. Select
      Network
      Virtual Routers
      and select the virtual router.
    2. Select
      Redistribution Profile
      and
      IPv4
      or
      IPv6
