I am trying to use DNS server and on "ping google.com" VPP is crashing
Color me unsurprised. Please fix your configuration, to the point where
first-order obvious errors have been eliminated. It looks to me like the
"binary-api dns_name_server_add_del 8.8.8.8" command has been truncated:
Aug 13 21:31:10 test1-vpp vnet[853]: unknown input `add_del 8.8.8.8
Aug 13 21:31:28 test1-vpp vnet[853]: dns cache: add / del / clear required..
Aug 13 21:31:36 test1-vpp vnet[853]:
vl_api_dns_resolve_name_reply_t_handler:2556: ip4 address 23.75.7.244
Aug 13 21:32:24 test1-vpp vnet[853]: dns cache: add / del / clear required..
Aug 13 21:34:43 test1-vpp vnet[853]: resolve_event:247: name server 8.8.8.8
backfire
Here is the config that I use on my home gateway.
uncomment { nat44 add identity mapping external GigabitEthernet3/0/0 udp 53053 }
uncomment { bin dns_name_server_add_del 8.8.8.8 }
uncomment { bin dns_enable_disable }
$ ping google.com # on my desktop, behind the vpp gateway
