SLX 9740 and VRF local-as

Pawe — Wed, 24 Feb 2021 06:21:39 GMT

Is there really no option to create VRF with different local-as on SLX9740 ?

Cant find any option to do this… and also cant find any manual that explain that it is possible

Is this different than 9540?

vrf foo
address-family ipv4 unicast
router bgp
address-family ipv4 unicast vrf foo
local-as 4556

yes it is

For example

(config-vrf-RKGM01)# address-family ipv4 unicast
(config-vrf-RKGM01-ipv4-unicast)# ?
Possible completions:
arp            Address Resolution Protocol (ARP)
bgp            Set next-hop for BGP
describe       Display transparent command information
do             Run an operational-mode command
exit           Exit from current mode

help           Provide help information
import         Apply a route-map filter on the routes to be imported
ip             The Internet Protocol (IP).
max-route      Maximum number of routes allowed in this routing table
no             Negate a command or set its defaults
pwd            Display current mode path
route-target   Configure Target VPN Extended Communities
top            Exit to top level and optionally run command

As You can see no router bgp for vrf instance

It looks like there is no local-as option for ipv6 unicast - but it is in ipv4 unicast for VRF

Looks like bug.

Can confirm on latest version, that this function seems to be missing for ipv6 unicast.
