Route Redistribution

Create a redistribution profile.
Select
Network
Virtual Routers
and select a virtual router.
Select
Redistribution Profile
and
IPv4
or
IPv6
and
Add
a profile.
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).
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.
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 blacklist 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.
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.
