Hello,

I am asking you for a little help, I just got an ASR9001 router and I am a
little confused with the IOS XR completely different from my ASR1001.

1- First problem, ISIS seems not to work

on my ASR1001X I have:
interface TenGigabitEthernet7/1
 mtu 1600
 ip address 192.168.1.1 255.255.255.252
 ip router isis
 mpls label protocol ldp
 mpls ip

router isis
 net 49.0001.0000.0000.0450.00
 is-type level-2-only
 metric-style wide
 redistribute connected
 !
 address-family ipv6
  multi-topology
  redistribute connected
  redistribute static
 exit-address-family

connected on this port, I have the ASR9001 with in conf:

interface TenGigE0/0/2/0
 mtu 1600
 ipv4 address 192.168.1.2 255.255.255.252

router isis WanCmp
 is-type level-2-only
 net 49.0001.0000.0000.0452.00
 address-family ipv6 unicast
 !
 interface TenGigE0/0/2/0
  address-family ipv4 unicast
  !
 !
!


but when i put sh isis topo

IS-IS phibee paths to IPv4 Unicast (Level-2) routers
System Id       Metric  Next-Hop        Interface       SNPA
ASR9001  --

Anyone have a idea of the problems ?


2- SSH/Telnet access to the router

currently I have to connect the ASR9001 router via the MgmtEth0 / RSP0 /
CPU0 / 0 port to access it.

Unable to go through the wan classic TenGigE0 / 0/2/0 interface

in my configuration, i have:

telnet vrf default ipv4 server max-servers 10

line console
 exec-timeout 1440 0
 escape-character 0x5a
 session-limit 10
 disconnect-character 0x59
 session-timeout 100
 transport input telnet ssh
 transport output telnet ssh
 transport preferred none
!
line default
 exec-timeout 1440 0
 access-class ingress admin-nets
 transport input all
 transport output telnet ssh
 transport preferred none

vty-pool default 0 5 line-template default
control-plane
 management-plane
  out-of-band
   interface TenGigE0/0/2/0
    allow SSH peer
     address ipv4 192.168.0.0/21
    !
    allow Telnet peer
     address ipv4 192.168.0.0/21
    !


ssh server v2
ssh server vrf default
ssh server vrf Mgmt-intf
end


if i want connect on wan interface, i have all time a connexion refused
