CCNA Skills Integration Challenge PT Activity 8.6.1 - Task 5
Task 5: Configure Inter-VLAN Routing
Step 1. Configure each Branch router for inter-VLAN routing.
Using the addressingtable for Branch routers, configure and activate the LAN interface for inter-VLAN routing. VLAN 99 is the native VLAN.
Step 2. Verify routing tables.
Each Branch router should now have sixdirectly connected networks and one static default route

Prepare Branch routers:

Go to the switch B1-S1 and inter vlan-routing commands:

And set the default gateway for allBranch switch:
B1-S1(config)#ip default-gateway 10.1.99.1

Finally step is check the ip routing table on the B1:

B1#sh ip rou
Codes: C - connected, S - static, I - IGRP, R - RIP, M -mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

Same configuration apply for other switch => B1-S2 and B1-S3 and routers=> B2 (switch B2-S1, B2-S2, B2-S3), B3 (B3-S1, B3-S2, B3-S3), but with appropriate ip address.
