Hi

First, to export some route as an external route to OSPF, it must be created
by some other protocol. Perhaps you have to add static or direct protocol to
your config? If the prefix 77.71.22.23/32 is e.g. on dummy0, then it will
not be exported through export filter, but propagated as internal route.
The interface has to be enabled in order to propagate its prefixes.

Second, does not make sense to set both ospf_metric1 and ospf_metric2
attributes, as external route may be either Type1 or Type2.

Third, i would suggest to disable rfc1583compat option, it may mess with that.
