cdist-type__bird_filter(7)¶

NAME¶

cdist-type__bird_filter - Create a named filter to use in configuring bird.

DESCRIPTION¶

This type writes a configuration file defining a filter named __object_id for the bird internet routing daemon. It is guaranteed that all filters defined through this type will be loaded before any other protocol defined using the cdist __bird_xxx types, except functions. However, note that if two filters have a dependency, they will be loaded in alphabetical order, so some care may need to be taken in the naming.

This type takes it’s input through stdin, expecting valid filter statements as per the bird configuration file syntax. The standard input will be printed out between a filter __object_id {n … n}, so only the inner statements are needed.

EXAMPLES¶

# Setup bird, a filter and open a BGP session.
__bird_core --router-id 198.51.100.4

require='__bird_core' __bird_filter bgp_export <<- EOF
    if (source = RTS_DEVICE) then accept;
    reject;
EOF

require='__bird_core' __bird_bgp bgp4 \
    --description "a test IPv4 BGP instance" \
    --ipv4-export "filter bgp_export" \
    --[...]
