6VPE (RFC 4659) Technology/Architecture on ASR9K/IOS XR
I'm a POC for 6VPE to test the function in some ASR9K boxes on the network that I operate and is going okay, but I'm with some doubts ...
Basically the scenario includes:
2 x CE routers (CE1, CE2) 3 x 6VPE routers (PE1-XR, PE2-XE and PE3-XR) 2 x P/RR routers (P1, P2)
Following the assumptions ...
In IOS-XR you need an IPv6 NH in order to activate the IPv6 AF for an IPv4 BGP session. If you don't have an IPv6 NH, then the IPv4 BGP session won't even come up. The above was done to protect against misconfiguration, because otherwise you would get a misleading v4 mapped v6 address as NH. If you have an IPv6 NH, then the IPv4 BGP session with the IPv6 AF will come up. If afterwards you remove the IPv6 NH, then the session deliberately remains up and you get a misleading v4 mapped v6 address as NH.
I would like to know the following questions, if possible
I can't have an IPv4 address as next-hop for IPv6 prefixes?
I must display an IPv4 address as next-hop for IPv6 prefixes?
Some any news for the progress in correcting the DDTS CSCuj74543?

Internet security is important with the increasing attacks that are happening every day. Many internet and browsing security solutions exist, but some are not very easy to use or maybe the question is how can I enable them?
