MPLS experiment

1. The experiment purpose

master VPN Configuration and DR and DT value

2. Experimental topics

3. Configuration experiment

1. Experimental Topology

2. Configure public network related configurations

1. Access to the public network

1. To configure ip And loopback

R2

R3

R4

R7

2. Use OSPF Connect the public network

R2

R3

R4
because 4-7 Give way between 2/3 know , however 7 It is the customer who sets 0/0/2 Bit silent interface

R7
The default solution is not to establish a neighbor to access the public network

3. Result display

2. Use MPLS Collocation environment

R2

To configure MPLS

Open the protocol on the interface through which the tag passes

R3
To configure MPLS

Open the protocol on the interface through which the tag passes

R4
To configure MPLS

Open the protocol on the interface through which the tag passes 【 And r7 Failure to establish neighbors is regarded as pc Can 】

result

3. Use VPN Configure the outer end of the connection

R2 Space
B1

A1

Specify the space at the outer end
B1

A1

result
double up And coexist 【 Because they are in the two routing tables vpna1 And vpnb1 No conflict 】

R4 Space
B2

A2

Specify the space at the outer end
B2

A2

result

4. send R2 And R4 Use bgp establish MPLS Special neighbors 【mp-bgp】

R2

R4

3. Configure customers ip And loopback

R1

R6


R5


R7

4.A1 perform RIP

R6

R2

result

5.A2 perform OSPF

R7

6. Two way republication

R2


R4


result

7. Static and direct connection are sent by republishing

B1
R1 Go to R5 The next jump 【 Direct route and static route 】

stay B1 Next jump in middle space

Space republish

result

B2
Have learned B1 The routing

R4 Learn direct routing

result
R4 After learning routing

take R4 Of 3.0 And 4.0 Republish to R2

R5 Go to R1 The next jump 【 Direct route and static route 】

result

4. Summary of the experiment

The experimental operation is not difficult, as long as the idea is clear, it is easy to deal with , No major problems were encountered during the experiment . Mainly understanding space , Its unique feature can separate two private network segments . It mainly depends on RD And RT Value to judge ！
