Hi I need to know, if I can create a layer2 bridge-domain and apply them to multiple router ports on a Cat8300 (running in the IOS-XE mode). For example something like this: interface bdi 100 ip address 10.10.10.1 255.255.255.0 interface giga...

Hi DMVPN Pros Maybe a DMVPN hero can help me out. I have a DMVPN setup with multiple spokes that are behind the same CGN (mobile 4G network). So there is a possibility that 2 CPEs may have the same public IP address after processing the CGN. Is this ...

Does anyone also see DUMPER crashes related to the ifindex_server process on his ASR9k? It looks like it's something with the snmp process... I have an open TAC but it's not a known bug. Maybe anyone else has also this problem...?

Is this still not supported?

Thank you for the document. The document describes the Spoke-to-Spoke Tunnels. What I like to know is, if the Spoke-to-Hub tunnels will also have problems, if two Spokes are translated to the same public IP address.

The more routers I have, the greater the probability that two will get translated to the same Public IP from the ISP, when he is doing CGN.

It's 6.2.3 with A9K-RSP880 and A9K-48X10GE-1G. ASR9006. I tried to restart the process manually, but since then I can't query some SNMP values anymore... and it's still crashing all the time. log messages:Aug 20 01:50:53 cybl-ch-gtg-pcr-001.cyberlink...

bridge-domain on Catalyst 8300

DMVPN and CGN (or NAT in general)

ASR920 file copy is extremely slow

Is "crypto isakmp key" address more-specific?
