heres a (final/working) config in case anyone else wants to do this:

===================

crypto ikev2 proposal gcp-ikev2-proposal-1

encryption aes-cbc-128 aes-cbc-192 aes-cbc-256

integrity sha1 sha256 sha384 sha512

group 2 5 14 15 16

!

crypto ikev2 policy gcp-ikev2-policy-1

match fvrf any

proposal gcp-ikev2-proposal-1

!

crypto ikev2 profile gcp-ikev2-profile-1

match identity remote address gcp.gcp.gcp.gcp 255.255.255.255

identity local address me.me.me.me

authentication remote pre-share key xxxxxxxxxxxx

authentication local pre-share key xxxxxxxxxxxx

lifetime 10800

!

crypto ipsec transform-set gcp-tset-1 esp-aes esp-sha-hmac

mode tunnel

!

crypto ipsec profile gcp-ipsec-profile-1

set transform-set gcp-tset-1

set pfs group14

set ikev2-profile gcp-ikev2-profile-1

!

interface Tunnel0

ip address 169.254.0.2 255.255.255.252

tunnel source me.me.me.me

tunnel mode ipsec ipv4

tunnel destination gcp.gcp.gcp.gcp

tunnel protection ipsec profile gcp-ipsec-profile-1

!

===================

And then configure BGP or maybe static routes as required.

After adding in the Tunnel0 interface config it just started working

straight away. So I guess my config was right all along, its just some

other aspect of IPSEC that wasnt happy with something missing… Yay

misleading debug output. :-/

Hope that helps someone else.

Also beware of

recently did a upgrade on two ASR9k1’s from 4.2.3 to 5.1.3

Thou I didn’t have the space issue, Here is 1 things you can try before hand –

‘admin install remove inactive’

Befogging upgrading you may will want to install the following SMU’s

CSCud98419

CSCud37351

CSCud54093

 

You will need to install the fpd so it will upgrade the fed upon boot or manually.

had ‘fpd auto-upgrade’ in my admin config. So it did it automatically

This is what we installed after we did the pre-requs:

asr9k-fpd-px-5.1.3

asr9k-k9sec-px-5.1.3

asr9k-mgbl-px-5.1.3

asr9k-mini-px-5.1.3

asr9k-px-5.1.3.CSCut52232-1.0.0

asr9k-px-5.1.3.sp7-1.0.0

asr9k-px-5.1.3.CSCur72219-1.0.0

asr9k-px-5.1.3.CSCur83427-1.0.0

 

It’s also possible to re-partitioning the disk to get some extra space(300M). Executing the re-partitioning is not service impacting.
