Every time when set configuration bgp, you need set AS-NUBER
```
set protocols bgp xxx
set protocols bgp xxx neighbor 10.10.1.2
set protocols bgp xxx addresss-family
```
It would be nice to add function like ' local-AS', which is set first time (one time) and value of this function is as-number for default.
It will be convenient for configurations.
```
set local-as xxx
set protocols bgp
set protocols bgp neighbor 10.10.1.2
set protocols bgp address-family
set protocols bgp neighbor 100.10.4.44 local-as 11111
```
If local-as used for neighbor, this have more priority and rewrite default value.
