[nsp] Backup on PRI

[Nick Kraal]

We have 6 E1 links between one of our PoPs and need extra bandwidth
el-pronto to ease congestion before a bandwidth upgrade is commissioned to a
T3. There is an ISDN PRI between them and would like to use this as a
temporary E1 dial solution. The PRI dials perfectly but notice that the
loading between the links is unbalanced -only about 500kbps on the PRI
Virtual Interface. We use OSPF and have place "maximum-paths 8" in the OSPF
configuration. Does OSPF loading over 6 links really work? Any ideas?

Much thanks in advance.
