SUMMARY

Fixes #826

1. where the eigrp output, has additional FD(Feasible distance) and RD(Reported distance) in via output.
   e.g. current: via 10.254.11.9, TenGigabitEthernet1/1
   e.g.new: via 192.168.100.1 (130816/128256), GigabitEthernet0/0
   Add match and capture values in two new lists.

Value List ADV_FD (\d+)
Value List ADV_RD (\d+)

2. the new output also has the via output with no starting spaces, changed "\s+" to "\s*" for start of line matches.

e.g. of additional fields. after
