Static Redistribution and Community Application
Customers that do not speak BGP must also have the appropriate communities applied for
the peering filters and service levels to work correctly. The easiest method is to combine
route tags with route maps to ensure that the appropriate BGP communities are
assigned to each prefix when the static routes are redistributed into BGP. The route tags
and service levels are shown in Table 9-6.
Table 9-6
Service Levels and Associated Route Tags
Service Level

Gold
500
Silver
510
Bronze
520
The route tags are specifically matched to the BGP communities for each service level to
increase readability and maintain consistency. The redistribution route maps are shown in
Example 9-10.

The only prefixes allowed in the redistribution are those with a tag that specifically includes
them in a particular service level.
