Lets Play with BGP

1. Configure IP Address as shown in the diagram
2. Configure Loopback Address as shown in the diagram
3. Configure AS number as shown in the diagram
4. Configure eBGP between AS
5. Configure OSPF in AS 1
6. Configure AS 1 in such a way so
R1, R10 and R11 should be in the AS 64512 and
R9, R12 and R13 should be in the AS 64534
Other AS should see only AS1 not Private AS Number when they receives routes
Inside Sub-AS i.e. 64512 and 64534 full-mesh iBGP should be configured with the most scalable manner
Hint (R1 and R9 should be Route-Reflector for the AS 64512 and 64534)
Configure eBGP between R11 and R12
7. AS 2 have 192.168.120.0/24 network on his AS and Currently this network is propagating in BGP from AS 2.
For some reason a part of that network (192.168.120.248/29) belongs to AS1 configure the needed router to
achieve the goal with keeping this informaiton on mind.
8. By default AS1 is the shortest path to go to AS3 from AS2. Because of Bandwidth Limitation AS 1 should not receive those
packets which destination IP do not belongs to AS1. Configure Accordingly.
VERIFY
9. Shutdown the fa0/0 interface of R9 and do ping to 8.8.8.8 with source IP 9.9.9.9 (Ping should be successful)
10. Do ping to 192.168.120.249 from R8 with source IP address 8.8.8.8 (Ping should be successful)
11. Do ping to 3.3.3.3 from R2 with source IP 2.2.2.2 traffic should not go from AS 1
12. You may have notice r> in some routes in AS 1. Find out the reason of that.

Site-to-Site IPSec VPN Cisco-Juniper

Image
Site-to-Site IPSec VPN Cisco-Juniper :   Scenario! Here in this LAB we have seven routers. R1, R2 and R3 routers represents Branch Router. R1 is working here as the HQ router and R2 and R3 as the Branch Router. R1 and R2 routers are from Juniper Networks and R3 router is from Cisco Inc. R4 router is working as an internet router. Other routers (R5 to R7) are working here as an end device. Task 1.       Configure Policy-based site-to-site VPN. 2.       Consider R4’s loopback address as internet route. 3.       R5 and R6 are configured as server so these servers should be reached from Branch Office too. 4.       Both Branch i.e. R2 and R3 should get internet from HQ i.e. R1 5.       In HQ router we have three zones named SERVER, INTERNET and INTRANET. SERVER Zones belongs to R5 and R6. INTERNET Zone belongs to R4 and INTRANET Zone belongs to the i...
