Static route issue

[shahulhameed]

Hi Friends

I have C-3560 switch and C819G-4G-G-K9 router for internet access. The Gi port of C819 router has been configured with IP of 20.20.20.1 connected to gi 0/1 port of C-3560 ip configured 20.20.20.2. The vlan 10 has created for users. My pc IP is 10.10.10.20. I enabled ip routing and configured static route.

01. I can able to ping my PC and 819 router interface IP from 3560

02. From my PC able to ping gateway and interface IP of 3560.

Please advise I am not able to ping 819 interface IP from my PC and not able to ping the DNS IP of the 819 router. I have attached configuration of 3560, 819 and ping from pc.

Thanks and Regards,

Shahul Hameed.

Hi this might not be how you want to sort it but looking at your configs quick thing i would do is create a router on a stick setup , create vlan 10 at layer 2 on the e891 as well as vlan 100 , set the sub interfaces for vlan 10,100 on the 891 and set the switch as a trunk connection then set your default gateway as the router itself or ip route 0.0.0.0 0.0.0.0 (interface) dont have default route and a default gateway at the same time

see this doc for that setup good guide

http://www.firewall.cx/cisco-technical-knowledgebase/cisco-routers/336-cisco-router-8021q-router-stick.html

2nd option create dynamic routing between 891 and the switch and advertise all subnets so everything can reach each other

Either of these options should get you going

Hi Mark

My intention is give at least internet access for employees if their office LAN failed.  I have configured IP SLA but it is not working. Trunk port will not use for my scenario. Because 3G or 4G ISP not giving static IP. 

Please advise how can I configure my edge switch access internet if the primary link failed ?

Thanks and Regards,

create a static route in your 819 router to tell how to reply your pc ip address range 10.10.10.0/24 via C-3560 interface 20.20.20.2

ip route 10.10.10.0 255.255.255.0 20.20.20.2
