2. TRUNK

3. INTERVLAN ROUTING

4. DHCP

5. OSPF

6. FRAME RELAY

7. BGP

8. ETHERCHANNEL

9. ROUTE REDISTRIBUTION 

with topology like this belowSuperlab 9Superlab 9Until NXT-Core-Network & NXT-R1 I can ping but after that device I can't ping & access what I miss for configuration? So I can ping or access every server

Hi, 

Please run following commands on both switches (Keep in mind the Port numbers)

 

NXT-CORE-NETWORK(config)#interface range gigabitEthernet 1/0/7-8

 

NXT-CORE-NETWORK(config-if-range)#no switchport 

 

NXT-CORE-NETWORK(config-if-range)#channel-group 4 mode active

NXT-CORE-NETWORK#

I use Packet Tracer version 7.1.0.0222. do you want the link download for that PT?
From above topology I success config for DHCP, trunk, Etherchannel & intervlan routing but I think for OSPF, Frame Relay, BGP & Route Distribution config is failed that show from PT file(from Laptop to Multi layer switch NXT-Core-DC & router R1 serial 0/0/0 ) I can't ping data center server & ISP Network server.

Hello,

 

on router NXT-R1 you need to redistribute BGP into OSPF:

 

NXT-R1(config-router)#redistribute bgp 100 subnets

Hi, 

I want to share some information with you. 

There is no default route information added in OSPF from the router "NXT-R1" because this is a border router between our local LAN and ISP. 

 

Your OSPF configuration must be as below on NXT-R1 router.

router ospf 1

log-adjacency-changes

network 192.168.1.0 0.0.0.255 area 0

default-information originate

 

Why no redistribution between OSPF and BGP?

This is a border router between LAN and WAN network so in the real world it is not possible to router local subnet on the WAN network and second think NAT is already placed on router in the correct way. So we need to troubleshoot the routing issue.

Thanks for your solution & your suggestion now the laptop/PC can access the ISP network server.
And for data center multilayer switch NXT-CORE-DC still can't access, what configuration I missed

Hi,

Port channel between "NXT-CORE-DC" and "NXT-CORE-NETWORK" is not configured properly. You have to reconfigure the port channel.

Ok thanks a lot

Just configure redistribution  on NXT-R1 for ospf and bgp.

Refer below configuration.

router ospf 1

redistribute bgp 100 subnets

exit

router bgp 100

redistribute ospf 1

exit

@vyasr2010 Dont mind:

is it possible to redistribution from Local IP address (LAN) to wan IPs in the real world? I hope you didn't check the lab. The router name, where is it installed, and what is his task? all are mentioned clearly.
