BGP AND OSPFv3 In MSR Series

 

 

Keywords: MSR;BGP;OSPFv3;IPv6

I            Requirement for the diagram

Using OSPFv3 as IGP in AS65009. RouterA establish EBGP with RouterB. RouterC is an inner Router of AS65009 and a none BGP router. Realizing import routing between BGP and IGP.

Device List: RTA,RTB,RTC

CMW Version: Version 5.20, Beta 1105P01

II          Network topology

Figure 1 BGP Import Routing info with IGP  

IP address list：

Device	Interface	IPv6 address
RTA	E0/0	1::1/64
	E0/1	1:1:1::1/128
RTB	E0/0	2::1/64
	E0/1	2::2/64
RTC	G0/0	2::2/64
	LoopBack1	3:3:3::3/128

IV       Result Check

1) The IPv6 routing table of RTC

From the table we can see that RTC learned the routing info that can get to RTA from RTB. Now, the loopback address can ping eachother of RouterA and RouterC.
