Guys,
Hope I won't be banned for spamming the forum with so much questions ;-)
While creating a service that includes enabling features on Cisco NX-OS, I've just found that when I destroy the service instance, the configuration applied by the NED, first removes the features, and then the config sections applicable to this feature, which just can't get through on the NX-OS platform.
The config diff:
device NX_LEAF112 {
config {
nx:feature {
- bgp;
nv {
- overlay;
}
- vn-segment-vlan-based;
}
nx:nv {
overlay {
- evpn;
}
}
nx:vlan {
vlan-list 72 {
- vn-segment 20001;
}
}Is then applied by the NED:
<< 10-Dec-2019::11:10:19.428 user: rslaski/2689 thandle 1078245 hostname nso1.sdn.lab device NX_LEAF112 SET_TIMEOUT

no router bgp 65001
no feature bgp

!
but when features have been removed
NX_LEAF112(config)#

the un-configuration commands can no longed be applied:

Any help for a rookie from the experts would be appreciated.
