Hi all,
I am labing MPLS L3 VPNs, and as I am trying different PE-CE routing protocols, I stumbled on a point where IS-IS is not being shown as an option to be redistributed into BGP as you can see below:
RP/0/0/CPU0:PE12#
RP/0/0/CPU0:PE12#sh run router bgp
Sun Mar 16 15:29:25.860 UTC
router bgp 240
address-family ipv4 unicast
!
address-family vpnv4 unicast
!
neighbor 14.1.1.1
remote-as 240
update-source Loopback10
address-family vpnv4 unicast
!
!
vrf ccc
rd 240:300
address-family ipv4 unicast
redistribute connected
redistribute static
!

RP/0/0/CPU0:PE12#conf t
Sun Mar 16 15:30:00.347 UTC
RP/0/0/CPU0:Mar 16 15:30:00.887 UTC: config[65742]: %HA-HA_WD_LIB-6-REG_PROC_SUCCESS : Memory state registration is success
RP/0/0/CPU0:PE12(config)#
RP/0/0/CPU0:PE12(config)#router bgp 240
RP/0/0/CPU0:PE12(config-bgp)#vrf ccc
RP/0/0/CPU0:PE12(config-bgp-vrf)#address-family ipv4
% Incomplete command.
RP/0/0/CPU0:PE12(config-bgp-vrf)#address-family ipv4 uni
RP/0/0/CPU0:PE12(config-bgp-vrf-af)#
RP/0/0/CPU0:PE12(config-bgp-vrf-af)#
RP/0/0/CPU0:PE12(config-bgp-vrf-af)#redistribute ?
application OnePK application routes
connected Connected routes
eigrp Enhanced Interior Gateway Routing Protocol (EIGRP)
lisp Locator/ID Separation Protocol (LISP)
mobile Mobile routes
ospf Open Shortest Path First (OSPF)
rip Routing Information Protocol (RIP)
static Static routes
subscriber subscriber routes
RP/0/0/CPU0:PE12(config-bgp-vrf-af)#redistribute
As you can see, there is no IS-IS in the options above. What am I doing wrong?
This is the version of IOS XR I am using on EVE-NG:
RP/0/0/CPU0:PE12#
RP/0/0/CPU0:PE12#sh ver | i image
Sun Mar 16 15:33:27.843 UTC
System image file is "bootflash:disk0/xrvr-os-mbi-6.6.2.10I/mbixrvr-rp.vm"
RP/0/0/CPU0:PE12#
RP/0/0/CPU0:PE12#
TIA.
Solved! Go to Solution.

Hi @Wassamba Muyengu ,
It is supported in more recent IOS-XR versions.
By the way, the utilization of isis as a PE-CE routing protocol is very marginal in the production networks worldwide.
