We're booting out-of-the-box ISR1100 devices with dhcp.
The switch gets an ip from DHCP and TFTP location for config file.
example: tftp:/cisco/configs/<device mac addr>.cfg
this works normally and the router downloads the config file which contains basic configuration.
AAA, NTP SNMP etc..
However, when applying the downloaded config.
All config i applied, except the service instance on Gi0/0/0 interface
Example:
interface GigabitEthernet0/0/0
no ip address
negotiation auto
no cdp enable
service instance 5 ethernet
description ipo_mgmt
encapsulation dot1q 5
rewrite ingress tag pop 1 symmetric
bridge-domain 5
!
!
!
interface BDI5
ip address 10.32.157.3 255.255.255.0
!
But we're instead seeing this config in gi0/0/0 when using console to access the router.
!
interface GigabitEthernet0/0/0
no ip address
negotiation auto
no cdp enable
!
The router applies all configuration except the "service instance" statement on the uplink. And we lose connectivity.
We're using IOS XR 16.07.01
