Hi,


The LSA type 4 is generated by ABRs and describes reachability to the ASBR.


The GRE Tunnels in IPv6 provides connectivity between 2 or More IPv6 Networks over IPv4, In MPLS it's being implemented because MPLS doesnt support IPv6 natively yet.


There are multiple ways 2 carry IPv6 Over MPLS:


1- 6PE.

2- 6VPE.

3- AToM (The payload is layer-2 Frames).

2- MPLS VPN Solution: This solution uses GRE Tunneling to carry IPv6 Over MPLS-VPN, The tunneling techniqes are:


1- 6to4.

2- IPv6 Over IP.

3- IPv4 compatible IPv6 Tunnels.

Hi,


You use it when you have 2 Or more IPv6 Domains needs to be connected over abn IPv4 or MPLS domains.

Ali,


As I responded on another post, an LSA type 4 is generated automatically by all ABRs (except the area where the ASBR lives or stubby areas) for each an every ASBR. They are used to calculate reachability to the ASBR.
