Hello guys,
On ower Vyos server we have ower own ASNumber added and ip ranges, i have a friend who whants to add/announce hes own ASNumber and Ip Range on ower router, as Sub"Customer".
I know is sompting with Import/Export but i dont fiind any examples or i have to create a session with ower AS / 1 IPv4 ?
Can anyone give me a example for this ? Please
Thank you
Hi, CristianD
If I understood right take a look at this
https://docs.vyos.io/en/latest/configuration/protocols/bgp.html#route-selection-configuration
Also, what do you mean by problem?
Hello,
I didnt mention any problem, the link i think is for having 2 seprat nodes, not what i need.
One of my friend told me 1 need a seprate router, on witch to create ges BGP configuration, connected to my network, create rule with import,export.
Is this the way it is ? Or i can do it on the same router ? My one
Hi Cristiand,
It`s depends , if you have your own public AS and your customer needs to announce their prefixes (these prefixes are their own). Therefore, you must speak to your local ISP to allow you to cross traffic with these
or
Also , you can create an ebgp session with your customer and you only need to do the policy import/ export ,this AS allows traffic to cross over to your upstream ISP.
You can configure all bgp sessions on one router.
Add policy prefix-list, route-map for import. For example with a biggest local-preference.
And update your route-map to neighbours who’s you want to send new prefixes for export.
Hello guys, what is the easy way/solution ?
Maybe I can’t get some information.
Is the customer has his own router with his own ASN and own prefixes?
If yes, just create a new one BGP session with him. And export his prefixes to ISP’s.
If for some reason you want the second router, it depends on your network topology.
customer ASN => your ASN => ISP ASN
Hello,
The customer has his own AS and Prefixes, and 1 server with Vyos only in case we need hem
We try to fiind the easy solution, is not necesary each to have hes own router.
Hi CristianD
I think Viacheslav’s last comment is the most common solution , it’s just create a BGP session with him (EBGP ) and then you create the policy (import/export) that you need. It’ll be something like this :
customer ASN => your ASN => ISP ASN
finally, talk with your local ISP and announce these new prefixes (if it is necessary )
Hello, i made the server with vyos, i setup hes as and prefixes on hes router.
I notice ower ISP to announce the new prefixes, is made.
The problem is the session and the config i have to do it in ower router and the way i connect cutomer router (on one port from ower router or from switch)
If someone can give us a hand to setup this i`m ready to pay , just pm me skype, fb, mail… (Paypal, By Card, Bank …etc)
This is sompting i never made and i dont whant to brake ower live router to make problems.
The session should i create on my router or on hes router ?
The cable connection betwin my router and hes router should it be made from one of my router port or from my switch to hes router ?
Bgp session should be configured on both sites. You configure own site, the customer configure own site. If you use switch you can add a separate vlan for it. The both options will work.
The only think i dont know is whant ips do i have to set on my session and whant ips i have to set on hes session.
Just took random ips.

My confusion is the sessions ips, should be on ower router set from hes ip range or ower iprange ?
On hes router i know it has to be ips from ower ip range, but on ower router i dont get it
It looks like i manage to connect both sessions / routers , only one problem left 
On both bgp sessions it say PfxSnt is 0 and PfxRcd

Re-check policy for export and import.
Check which prefixes you export to neighbor
show ip bgp neighbors x.x.x.x advertised-routes
Yea strange, it show my ip ranges it should show hes ones right ?
Fixed but, sessions work but its strange cuz i get
connect: Network is unreachable
When i try to ping 8.8.8.8 from the router
