EdgeRouterPro-8 config example with v1.9.0

After a lot of searching and trying I [Phil/ALS7] finnaly got a working config
Also thanx to drathir for his patience and support

Features

IPv4/IPv6 Tunnel via OpenVPN
dn42 DNS

How-To

--> still work in Progress

Basic EdgeOS knowledge is required
If you are using LoadBalancing make shure 172.20.0.0/14 is under 'PPRIVATE NETS'

1) you need to create all required fields in the registry --> look at Getting started

2) get a peer --> ask nice @ IRC

3) You need following data from the peer

--tunnel options, secret key --ASN from the peer --ip's

...

The data i used are the following:

Own ASN: AS111111
Own IPv4: 172.AA.AA.64/27
Own IPv6: fdBB:BBBB:CCCC::/48

Peer OpenVPN Remote Address: X.X.X.X
Peer OpenVPN Remote Host: X.X.X.Y
Peer OpenVPN IP for you: fdAA::BBB/64
Peer OpenVPN IP: fdAA::CC
Peer OpenVPN Port: 1194
Peer OpenVPN encryption: aes256
Peer ASN: AS222222
Peer BGP Neighbour IPv4: Z.Z.Z.Z
Peer BGP Neighbour IPv6: fdAA::CC

Copy OpenVPN key to the ErPro

copy vpn key to /config/auth/giveITaName

sudo su  
cd /config  
mkdir auth  
cd auth  
cat > giveITaName

now paste the key in the terminal window, hit return once and kill cat with CTRL+C
last thing to do is type exit

Create IPv4 OpenVPN Interface

Set up Interface vtunX -- i used vtun0

configure  
set interface openssh vtun0  
set interfaces openvpn vtun0 mode site-to-site  
set interfaces openvpn vtun0 local-port 1194   
set interfaces openvpn vtun0 remote-port 1194  
set interfaces openvpn vtun0 local-address 172.AA.AA.64  
set interfaces openvpn vtun0 remote-address X.X.X.X  
set interfaces openvpn vtun0 remote-host X.X.X.Y   
set interfaces openvpn vtun0 shared-secret-key-file /config/auth/giveITaName    
set interfaces openvpn vtun0 encryption aes256  

set interfaces openvpn vtun0 openvpn-option "--comp-lzo"  //if your peer support compression  

commit   
save  
exit

Now the ipv4 tunnel should be up&running

Check it with:

show interfaces openvpn    
show interfaces openvpn detail  
show openvpn status site-to-site

Create IPv4 BGP Session

Open Firewall

You need to open the firewall to local for the tunnel Interface on port 179/tcp

Configure the BGP Neighbor

You must not use AS before the as numbers !!

With this step you create the basic bgp session

configure  
set protocols bgp 111111 neighbor Z.Z.Z.Z remote-as 222222  
set protocols bgp 111111 neighbor Z.Z.Z.Z soft-reconfiguration inbound  
set protocols bgp 111111 neighbor update-source 172.AA.AA.64  
commit
save

When commit this configuration you should be able to see a BGP neighbor session start and come up.
You can check this with:

show ip bgp summary

Set route to blackhole

so bgp can announce the route

set protocols static route 172.AA.AA.64/27 blackhole  
commit  
save

Announce prefix to BGP

set protocols bgp 111111 network 172.A.A.64/27  
commit  
save  
exit

You should now be able to see networks being advertised via

show ip bgp neighbors Z.Z.Z.Z advertised-routes

Define Nameservers

Now ping to 172.23.0.53 ... thats the nameserver we are using
If everything is allright it should work

NS Config

Enter the configure mode

configure
set service dns forwarding name-server 8.8.8.8  
set service dns forwarding name-server 8.8.4.4
set service dns forwarding options rebind-domain-ok=/dn42/ 
set service dns forwarding options server=/23.172.in-addr.arpa/172.23.0.53  
set service dns forwarding options server=/22.172.in-addr.arpa/172.23.0.53  
set service dns forwarding options server=/dn42/172.23.0.53  
commit
save
exit

Now try to access any .dn42 tld
