compatible-rfc1583
Syntax [no] compatible-rfc1583
Context config>service>vprn>ospf
Description This command enables OSPF summary and external route calculations in compliance with RFC1583
and earlier RFCs.
RFC1583 and earlier RFCs use a different method to calculate summary and external route costs. To
avoid routing loops, all routers in an OSPF domain should perform the same calculation method.
Although it would be favorable to require all routers to run a more current compliancy level, this
command allows the router to use obsolete methods of calculation.
The no form of the command enables the post-RFC1583 method of summary and external route
calculation.
Default compatible-rfc1583 — RFC1583 compliance is enabled.
export
Syntax export policy-name [policy-name…]
no export
Context config>service>vprn>ospf
Description This command associates export route policies to determine which routes are exported from the route
table to OSPF. Export polices are only in effect if OSPF is configured as an ASBR.
If no export policy is specified, non-OSPF routes are not exported from the routing table manager to
OSPF.
If multiple policy names are specified, the policies are evaluated in the order they are specified. The
first policy that matches is applied. If multiple export commands are issued, the last command entered
will override the previous command. A maximum of five policy names can be specified.
The no form of the command removes all policies from the configuration.
Default no export — No export route policies specified.
Parameters policy-name — The export route policy name. Allowed values are any string up to 32 characters long
composed of printable, 7-bit ASCII characters. If the string contains special characters (#, $,
spaces, etc.), the entire string must be enclosed within double quotes.
The specified name(s) must already be defined.
