BGP federal experiment

The experimental requirements are as follows


take ip After the address is assigned, start the analysis experiment
To make the whole bgp The loopback of the environment can access each other , will r2 r3 r4 Set Federation , Below r567 equally
Now start configuring as2 Of ospf The environment allows them to reach

Go and check them out ospf My neighbor table

No problem ,as2 After passing through , Start configuration bgp Environmental Science

In the configuration r2bgp Pay attention to the environment , Because only one device can be configured bgp, And because we need to configure Federation , So just go straight bgp 64512, But also declare your big size , All federal members should do this

Then declare that you are a loopback interface neighbor , Otherwise, the route cannot be reached , Declare to every neighbor

Although the federal , But because it is still in ebg peers , So we need to modify the federal border router ttl value

The others are the same


bgp When the configuration is complete , Check it out. bgp surface

Then start announcing the route

because ibgp There is horizontal segmentation, so we will r3 and r6 Make a reflection router

It is found that the loopback route has been obtained
