MPLS Layer 3 VPN Juniper Task 1. Configure physical, Loopback IP Address as shown in the Topology 2. Configure OSPF on the provider network for internal Connectivity 3. Configure MPLS on the provider network 4. Configure Provider's MPLS network in such a way so primary LSP should be via-JunOS1-3 when traffic goes to right side (i.e. JunOS1-4) and primary LSP should be via JunOS1-2 when traffic goes to left side (i.e. JunOS1-1). Both (primary / secondary) path should be display up/up all the time 5. Configure IBGP on the provider network AS number should be 1234 6. Configure provider (PE) routers in such a way so different vrf table should be created for each customer and configure static route to reach the customer network 7. Configure static route on the customer Router to reach the another network. 8. Make sure customer should be reach to each other Click here to get configuration file ! MPLS L3 VPN Juniper

1. For easy to remember Configure IP Address according to the below instruction (Configure 192.168.12.0 network in between R1&R2 and assign IP address 192.168.12.1 on R1 and 192.168.12.2 on R2 likewise 192.168.67.0 network in between R6&R7 and assign IP address 192.168.67.6 on R6 and 192.168.67.7 on R7)  2. Configure Loopback interface on AS200 with the help of Router name (For example R2 = 2.2.2.2/32, R3 = 3.3.3.3/32) 3. Assign AS Number 100, 400 and 300 on R1, R9 and R8 respectively 4. Assign AS Number 200 on the rest of the router 5. Configure OSPF on the AS 200 for Internal connectivity 6. AS200 working as a confederation network where R2, R3 and R4 belongs to Sub-AS 64555 and R5, R7 and R6 belongs to Sub-AS 64777. Configure accordingly. 7. Configure CBGP between R3&R5 and R4&R6. 8. In the Sub-AS R2 and R7 are working as a Route Reflector (RR) to solve the issue related to full-mesh on the Sub-AS. Configure Accordingly 9. In this lab I'm  using vSR...

BGP on Juniper for beginners! Here in this lab I’m going to do enjoy with configuring BGP on Juniper. You should have at least following knowledge before trying to configure BGP. 1 Sound knowledge about Routing Policy on Juniper Sound knowledge about IGP (OSPF, ISIS) What is BGP? Basic terminology of BGP (AS Number, IBGP, EBGP) When / when not need BGP? How BGP Works? Network Scenario Here in this Lab we have three different AS numbered AS10 which is configured on R1, AS20 which is configured on R2 & R3 and Finally AS30 which is configured on R4. We have a network 172.16.0.0/22 which belongs to AS10 configured on the Loopback interface of R1 and network 172.16.4.0/22 which belongs to AS30 configured on the loopback interface of R4. Now let’s move to the topology information SN Router AS Interface IP 1 R1 10 lo0.1 : 172.16.0.1/24 lo0.1 : 172.16.1.1/24 lo0.1 : 172.16.2.1/24 lo0.1 : 172.16.3.1/24 em0.0 : 192.168.12.1/24 2 R2 20 lo0...

1. First of all configure IP address on the interface. Put 192.168.12.1 on the fa0/0 interface of R1 and 192.168.12.2 on the fa0/0 interface of R2. Use IP network as below a.      For R1 to R2 = 192.168.12.0/24 (Assign 192.168.12.1 on R1 and 192.168.12.2 on R2) b.     For R2 to R3 = 192.168.23.0/24 (Assign 192.168.23.2 on R2 and 192.168.23.3 on R3) c.      Do same. 22. In the routing table of R1, RIP network should not appear which is located behind the Area 3 in   the topology but connectivity between Area 1 and RIP network should have. 33. Configure Backbone area in such a way so serial interface should be the primary link for the backbone network. 44. Configure Area 47 in such a way so R7 should only have default route to reach the external network and should not allow advertising any network from here. 55. Area 3 should be configured in such a way so R6 should only have default route to reach external networ...

Network Scenario Explanation! Suppose this is the network of ABC Bank Ltd. ABC bank has two branch offices with one Head Office.   Branch offices are located at East and West side respectively. Bank has purchased two links from Internet Service Provider. One link is L2 Link (Intranet) and another Link is L3 (Internet). Our goal is to configure our network in such a way so our L2 link should be the primary link of the Bank network and L3 should be the secondary link of the Bank network. If any problem arises in L2 network at that time traffic should automatically go from L3 network. Bank should not face any kind of connectivity issue. There are lots of technologies to achieve the goal. But here I’m going to configure DMVPN to achieve the goal. DMVPN is acronym from Dynamic Multipoint Virtual Private Network. I would like to say DMVPN as an engineering rather a protocol itself. DMVPN is not a protocol itself rather it is the combination of protocols. To configure DMVPN ...
