Hi, group
pls see the follow topo
R6------R5-----R4
/ /
r7 R3
R5/R4/R4 in area0
r5/r6 in area 5
r6/r7 in area 6 and is stub
it is obiously that we should assign area 5 as virtual area
now for security reason, we need to auth area 0 with md5. now
peoblem is appear: how deal with virtual area? we always see virtual area as
extened area0, so if we change virtual area with the same authentication
maybe all will OK bith in R5 and R6.
but now, just as I add "area 5 vir 133.3.5.5 authentication mess", (no any change in R5)the ospf
vir load full message appear and all r7 route will inject to R5.pls see below for detail
My quention is if it is OK now ,and we do not need to do more?
