Can´t see neighbor router

Fri Feb 24, 2017 12:29 am

Hi, I've got the following setup on an enterprise network with the pourpose of connecting two buildings trough an ethernet cable.


Router 1

Eth/01 Connected to internet
Eth/02 Lan 192.168.0.1
Eth/03 10.0.0.1/30 Connected to Router2


Router 2

Eth/01 10.0.0.2/30 Connected to Router1
Eth/02 Lan 192.168.881
 0 A S  0.0.0.0/0                          INTERNET1                 2
 5 ADC  10.0.0.0/30        10.0.0.1        Don Bosco                 0
 6 ADC  10.10.11.0/24      10.10.11.1      ether5                    0
 8 ADC  192.168.0.0/24     192.168.0.1     LAN                       0
 9   S  192.168.0.0/24     192.168.0.2     ether4_Temporal           1
                                           LAN               
10 A S  ;;; Enlace Piedra Buena
        192.168.88.0/24                    10.0.0.2                  1
This is basicly my routing table on Router one.

The problem is that I cannot reach Router 2 from Lan on Router 1 but I can get Router1 from Lan on Router2.

When I tried to trace route from router1 it says that host 0.0.0.0 timed out.

any help pleaseee

Does Router2 have the LAN Netowork from Router1 in routing table?
Also, post the routing table from Router2.

Just noticed that router1 is connected to router2's ether1. Is router2 on default config? If so don't ether1 will firewall and masq rules on it. Please check that or just use another port other than ether1.

Sorry they're not connected trough ethernet 1 but trough SFP ports on both of them. I can ping router 2 SFP interface from Router1 Console. I'll see if I can get router2 config.

Here it is the Router 2 Route List:

[code]#      DST-ADDRESS        PREF-SRC        GATEWAY            DISTANCE
 0 A S  ;;; Gateway Don Bosco
        0.0.0.0/0                          10.0.0.1                  1
 1 ADC  10.0.0.0/30        10.0.0.2        bridge-local              0
 2 A S  192.168.0.0/24                     10.0.0.1                  1

YOu need to create firewall rules (forward) on each router allowing communication between LANS. eg
add action=accept chain=forward comment="LAN Traffic" dst-address=192.168.88.0/24 src-address=192.168.0.0/24
add action=accept chain=forward comment="LAN Traffic" dst-address=192.168.0.0/24 src-address=192.168.88.0/24
