Ipv6 interface connectivity issue

In the Routing Fundamentals lab step 2.1 it instructs to configure the ipv6 address: set ge-0/0/1 unit 0 family inet6 address fda1::1/126 set lo0/0 unit 0 family inet6 address fda9::1/128 on vSrx1 and fda1::2/126 on vSrx2 On the next step it issues a successful ping on the local interface e.g. ping fda1::1 rapid count 25 on vSrx1 I have setup the ipv6 addresses as shown in the lab. However when i issue a ping it just responds with No route to host. The ping to the lo0/0 address works fine I have issued a run show route command and have noticed that the lo0/0 address is in the routing table but instead of the ipv6 addresses configured on the interface with the /126 mask i have a link local address route in the table instead with a /128 address

Basic IPv6 Reachability issue

From my router i can't ping my client either

IPv6 on Juniper SRX240

I am trying to enable IPv6 and use my SRX240 as a router (gateway) on internal clients. I'm pretty sure I am missing something though, I added the address to the interface but trying to ping it from a client returns no results

MX480 - 16.3 - 6VPE IPv6 Routes Hidden

Focus Search - The route I am concerend with is 2021:........ The interface ae44 is the link from the MX to a series of QFX switched where the end CE device is located. VLAN 2300 and 2301 are the redundant paths to the end device, I cna ping both the IPv4 and v6 addresses across the links

RE: MX480 - 16.3 - 6VPE IPv6 Routes Hidden

You are corect, there are no routes in inet.3 or inet6.3...All the routes and traffic flow are correct and work (by accident, maybe) for v4 but the issue is v6 and some of that very well can be a misunderstanding

effect of traffic-engineering bgp-igp-both-ribs on IPv6 routes

Hello, Does the command traffic-engineering bgp-igp-both-ribs have any effect on IPv6 routes iin inet6.3 table? in my lab, I have not been able to observe the replication of inet6.3 routes in inet6.0. is this expected behaviour or might I have missed something?
