Hi, all
According to rfc2328. p.175, when we have multiple intra-area paths to
ASBR,a intra-area path using non-backbone area should be chosen over
one using backbone area.
But I always have opposite result. doesn't Cisco's implementation yet
conform to rfc2328 in this respect?
Here's from my cisco 2501 router.
r2#sh ip ospf data
-------------------------------------------------omitted
Type-5 AS External Link States
Link ID ADV Router Age Seq# Checksum Tag
131.108.0.0 192.168.40.3 324 0x80000003 0xE930 0

r2#sh ip ospf border

i 192.168.40.3 [1562] via 172.16.30.33, Serial1, ABR/ASBR, Area 6, SPF

r2#sh ip route
-----------------omitted
O E2 131.108.0.0/16 [110/20] via 172.16.2.2, 00:03:38, Serial0
r2#
Could somebody explain this to me?
Thanks in advance.

Jaeheon
