Hi GS,
I have three routers Router A is HUB and Router B and Router C are Spokes.
Between routers A-B and A-C are running multilink PPP. However I noticed the
following that not appeared in normal HDLC connections:
CRIAJE-C#sh ip int brief
Interface IP-Address OK? Method Status

<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
S* 0.0.0.0/0 [1/0] via 192.168.246.49
CRIAJE-C#
Why 172.31.127.2/32 and 172.31.127.6/32 appeared in routing table as
directly connected? is it normal? 172.31.127.2 is the IP Wan address from
Router B. and 172.31.127.6/32 is the IP Wan Address from Router C.
After i enable eigrp in Router Central and Spokes:
In router Central:
!
router eigrp 100
redistribute static metric 1544 2000 255 1 1500 route-map
REDISTRIBUTED-EIGRP-STATIC
network 172.31.127.0 0.0.0.3
network 172.31.127.4 0.0.0.3
network 172.31.127.254 0.0.0.0
no auto-summary
!
ip http server
ip classless
ip route 0.0.0.0 0.0.0.0 192.168.246.49 tag 500
!
route-map REDISTRIBUTED-EIGRP-STATIC permit 10
match tag 500
!
In Spoke (Router C):
CRIAJE-2#sh run | b router eigrp
router eigrp 100
network 172.31.114.0 0.0.0.255
network 172.31.127.4 0.0.0.3
network 172.31.127.252 0.0.0.0
no auto-summary
!
But in router C (CRIAJE-2) appear one D EX route (D EX
172.31.127.2/32[170/15119872] via
172.31.127.5, 00:04:05, Multilink1) ... why if i'm not redistributed that
route.. ?????
