I need help configuring a static route

hfakoor222 · ‎04-15-2022

I cannot get any of my VPC'sto pint router R2

I can get them to ping segments attached to R2

I want to focus on pinging from PC2 (right side) to R2

EIGRP is configured everywhere, I have connections between PCS, but nothing seems to be getting to R3

I am attempting a GLBP project - i have subinterfaces configured on R3 and R2 pointing downstream, the interfaces themselves have no IP, except for the subinterfaceThe lab I'm piggybacking off of seems to be able to get to R2 through having subinterfaces ip addressed only

Baically i want help in configuring a static route to R2 from R3

Interfaces on R3

here is a routing table

here is the running config of R3

I would like suggestions on configuring a static route to move traffic from Pc2 to R2

Everywhere has connectivity except nothing seems to get past either router to get to R2

David Ruess · ‎04-15-2022

Hello,

A couple things I noticed.

-Interface g0/0.99 on R3 was shut down - not sure if that was intentional

-EIGRP is configured but auto-summary is on. Since you have discontiguous networks I would turn that off. That can wreak havoc on routing.

For a static route the syntax is: ip route <destination network> <destination mask> <next-hop ip (or) exit interface>

-David

Ive tried both 0.0.0.0 0.0.0.0 10.1.2.2 on R3

and 0.0.0.0 0.0.0.0 10.1.2.3 on R2 with no success in pinging R2

and I would like any suggestions

I will go ahead and turn off EIGRp auto-summary

David Ruess · ‎04-15-2022

So a default route is for saying if you don’t know where to send me go this way. What you configured was 2 default routes pointing to each other which won’t provide full connectivity.

For the full connectivity enter on all routers:

router eigrp 1

network 10.0.0.0 0.255.255.255

no auto-summary

then please post the sho up route and show up protocols for all 3 routers.

-David

hfakoor222 · ‎04-15-2022

I removed static routes and redid the eigrp commands

router eigrp 1

network 10.0.0.0 0.255.255.255

no auto-summary

for R2

no luck getting to R2 I can still get to the segments on the other side of the GLBP routers

Here's R2's config

I retried a static route

0.0.0.0 0.0.0.0 s0/0

and still no luck

Jon Marshall · ‎04-15-2022

You have used the same subnets on R2 and R3 eg. 10.10.1.0/24 but there is no L2 path between R2 and R3 ie. they are separated by a L3 link using 10.1.2.0/24 so that will not work.

You can't have the same IP subnet separated by another subnet, it won't route properly.

Jon

hfakoor222 · ‎04-15-2022

I changed s1/2 on R3 from 10.1.2.3 to 10.1.3.5 and get a not on same subnet

*Mar 1 00:23:59.935: IP-EIGRP(Default-IP-Routing-Table:1): Neighbor 10.1.3.5 not on common subnet for Serial0/0

and the packet gets lost in transit when pinging

*10.1.10.2 icmp_seq=1 ttl=255 time=228.349 ms (ICMP type:11, code:0, TTL expired in transit)
*10.1.10.2 icmp_seq=2 ttl=255 time=236.962 ms (ICMP type:11, code:0, TTL expired in transit)
*10.1.10.2 icmp_seq=3 ttl=255 time=234.256 ms (ICMP type:11, code:0, TTL expired in transit)
*10.1.10.2 icmp_seq=4 ttl=255 time=245.914 ms (ICMP type:11, code:0, TTL expired in transit)
*10.1.10.2 icmp_seq=5 ttl=255 time=231.994 ms (ICMP type:11, code:0, TTL expired in transit)

You misunderstood what I was saying.

Just realised, is your description in your first post wrong ie. R2 has no fa0/0 interface on it so do you mean R1 ?

Jon

MHM Cisco World · ‎04-15-2022

the SW is L2SW ?
If yes then
you need to config HSRP in both Router
you need to assign VIP of HSRP as Default GW in each PC
you need to be sure that the trunk between two SW is allow all VLAN.

hfakoor222 · ‎04-15-2022

The gateway for PC 2 is as follows

NAME : PC2[1]
IP/MASK : 10.1.10.102/24
GATEWAY : 10.1.10.254
DNS :
MAC : 00:50:79:66:68:00
LPORT : 20062
RHOST:PORT : 127.0.0.1:20063
MTU : 1500

PC2>

I also tried a 10.1.10.1 gateway same results

MHM Cisco World · ‎04-16-2022

10.1.10.254 <- this IP for what Router or SVI
