hi,we have 12410 GSR (PRP2) as internet gateway peering with 6 global ISP , and receive full internet routintg from them, CPU is high especaily at BGP scanner process,we are planning to enable IPv6 on this internet router so we can not expect what wi...

Hello,I currently have IPv6 deplyed but need to re-ip the network to another prefix.  Is there a way to deploy the new prefix on the VLANS and not have them advertised to clients until we are ready to cut over to the new prefix and then cut over to t...

Hi,Can anyone comment on the current state of development for IPv6 Multicast support for Service Providers who are using 6PE or 6VPE in their MPLS core.(6PE - SP is running MPLS in its IPv4 core, it uses IPv6-enabled provider edge (PE) routers to tra...

i am new to IPv6, to start with looking for what are the best practices, methodologies, standards, guidelines, architecture and security that will be adopted and the rationale of adoption vis-à-vis the provision of the IPv6? Can someone help me addre...

Hello all,I have posted this one in Security->VPN but probably it is better here, sorry for the duplicate.I am in the process of deploying ipv6 in my network and I had some difficulties figuring this out.Scenario is a Cisco 1921 acting as main router...

All,I read in rfc 4038 that representing IPv4 address in an IPv6 address should be like 2001::FFFF:192.168.1.1, which would be  2001::FFFF:c0a8:101, or 2001.2.3.4::FFFF:192.168.1.1 (2001:2:3:4:0:ffff:c0a8:101).  However, setting up NAT-PT any 96 bit ...

Hi,I know that this is simplifying things a lot, and ignore SLAAC etc, but:Is IPv6 essentially the same as IPv4 but with much larger addresses and you nearly always use a public IP address?By essentially the same I mean that in most situations you:Ha...

Hi,Is there any way to filter IPv6 routing updates ? I would like to prevent a router to propagate a default route further.The distribute-list command seems to be only for redistribution when filtering outgoing update. Francois

   Hi,I have one question.Why IPv6 came straight after IPv4 and ipv5 was not introduced?

Dear community members,I am rolling out ipv6 in my network and I am running in some "strange" issues in implementing ipv6 access lists.The following access list is applied to the ipv6ip tunnel providing connectivity to the v6 provider.ipv6 access-lis...
