* Fiber cable is in Port-33 in both sides

Which switch on provider (=dcl old) side?

• Correction Switch-1 Port-39 switch-1

Note: switch1, port33 is a 1gbit trunk port -> seems not to be the right one!

• first reset the used Arista switch

• Set up username and password
  

   *To be Done* 

• Set up the default route and the default gateway address
  

   (config)#ipv6 route ::/0 2a0a:e5c0:1:7::7 

• enable ipv6 all interfaces i.e(all interfaces are in vlan-1 by defaut)
  

  (config)#interface vlan 1

  
  

   (config-v1)#ipv6 enable

• check if the what is active
  

   (config-if-Vl1)#show active 

• if it works we will see this
  

   interface Vlan1
     ipv6 enable 

Port 39 in switch1 is not connected:

Et39                      notconnect   1        full   10G    Not Present       

Setting up Switch in Place 9

• So this is how it looks like from the beginning. * Frist we got the fibre-cable(up-stream) from the ISP (Nico), and we connected the fiber cable to our Arista switch (switch-1) in our side.

• Reseting the switch to factory default.
  • press

    ctl-c

    when the Arista is booting.
• once you pressed that you will be in the

  Aboot

  mode.
• Type

  fullrecover

  and press Enter to revert /mnt/flash to factory default
  state, or just press Enter to reboot: fullrecover. * At this point the Arista will be set to factory default

• Upgrading Arista

• getting ready a usb stick with fat32 format and coping the file into the stick

• * plug it into the switch and run the following commands

  switch1#copy usb1:/EOS-2GB-4.18.6M.swi flash:
  switch1#configure 
  switch1(config)#boot system flash:/EOS-2GB-4.18.6M.swi 
  

• finally reboot the arista

• Adding username and password
• The initial configuration provides one username, admin, that is not assigned a password.but we can set up a password to the default admin username.

  •  switch(config)#username admin secret <pasword-here> 

• Next steps are to set up the default route

•  (config)#ipv6 route ::/0 2a0a:e5c0:1:7::7 

• enable ipv6 all interfaces i.e(all interfaces are in vlan-1 by defaut)

(config)#interface vlan 1

 (config-v1)#ipv6 enable

• check if the what is active
  

   (config-if-Vl1)#show active 

• if it works we will see this
  

   interface Vlan1 ipv6 enable 

• configuring ipv6 end point or default static ip address
  

   ipv6 route 2a0a:e5c0:1:7:18 vlan 1 

Nice!

... all 4 up!

Im trying to create a redundant sfp connection from mikrotik to 2 aristas. First i assumed that the port-channel is propagated through mlag and 2 physically seperate interfaces will bond (in practice i named the two ethernet ports with the same port-channel number), but ive read some docs and port-channel can only bond ports on one physical switch. Since mlag is already active I assuming bonding the two mikrotik sfp ports and connecting it to 2 arista switches is enough. First test worked (crs all ports and sfpbond in bridge, arista port17-s confed to tag with vlan 15, arista interface conf: (#interface ethernet 17, #switchport access vlan 15) on both) unplugging one sfp caused few second outage, got ip-s from coworking.
Then I realized I only need 1 port for vlan tagging in crs for wlan.
Now on both aristas both port17 in #switchport mode trunk
crs confed as
ether24 and sfpplus1 in bridge
interface bridge port add pvid=15 interface=ether24 bridge=bridge
bridge=bridge vlan-ids=15 tagged=sfp-sfpplus1
untagged=ether24 current-tagged=sfp-sfpplus1
current-untagged=ether24
interface bridge set bridge vlan-filtering=yes

Adding bgp routing to switch5.place6

switch5-place6#configure 
switch5-place6(config)#router bgp 209898
! IP routing not enabled
switch5-place6(config-router-bgp)# router-id 0.0.0.25
switch5-place6(config-router-bgp)#bgp default ipv6-unicast
switch5-place6(config-router-bgp)#maximum-paths 4
switch5-place6(config-router-bgp)#   bgp listen range 2a0a:e5c0:1:8::/64 peer-group ungleich remote-as 209898
switch5-place6(config-router-bgp)#   neighbor ungleich peer-group
switch5-place6(config-router-bgp)#   neighbor ungleich maximum-routes 12000 
switch5-place6(config-router-bgp)#exit
switch5-place6(config)#ip routing
switch5-place6(config)#ipv6 unicast-routing
switch5-place6(config)#write 

hints for mikrotik:

• delete the port-channel
• et17: switchport mode trunk
• et17 NO channel-group

place9 is no more/ partially moved to place10
