| Description | From RFC2328:
Controls the preference rules used in Section 16.4 when
choosing among multiple AS-external-LSAs advertising the
same destination. When set to 'enabled', the preference
rules remain those specified by RFC 1583 ([Ref9]). When set
to 'disabled', the preference rules are those stated in
Section 16.4.1, which prevent routing loops when AS-
external-LSAs for the same destination have been originated
from different areas. Set to 'enabled' by default.
In order to minimize the chance of routing loops, all OSPF
routers in an OSPF routing domain should have
RFC1583Compatibility set identically. When there are routers
present that have not been updated with the functionality
specified in Section 16.4.1 of this memo, all routers should
have RFC1583Compatibility set to 'enabled'. Otherwise, all
routers should have RFC1583Compatibility set to 'disabled',
preventing all routing loops. |
