[rbak-nsp] SEOS and IPv6 DHCP

hello,

does anyone knows is SEOS 12.1.1.x (recent, or any) is able to assign IP
address via DHCPv6 (statfull) ?

From our tests, it looks like it supports statless operations +
statefull only for prefix delegation, but some CPEs support only DHCPv6
for IPv6...

If it is not supported, is it implemented in IPOS for SSR series ?

Haven't tested it yet, but as per the documentation for IPOS 16B it should work beginning from IPOS 16B but only with PPA3 cards and Spider cards.

PPA3 on SSR ? That's SmartEdge's chipset...

Yes, correct!

The “4-port 10GE or 20-port GE and 2-port 10GE Card” is using this chipset.
This card supports most of the subscriber features known from SmartEdge. Other cards are only supporting a subset (“Spider” card 20x1/10GE ) or nearly nothing (“NP4” card 10x10GE).

On SSR you really have to check, which features you need and the decide which cards to buy.

We’ve learned this lesson through many pain. And Ericsson also =;-)

Intersting...
So SSR will also suffer from PPA Crashes...

Btw, is there any reasonable SSR config for BRAS ?
I was wondering about 8801, but I'am bit sure now how about
functionality (BRAS) and if 100G port can work in 40G mode...

No PPA crashes observed here on SSRs. But we are still in migration phase, so there are not much subscriber sessions on those cards in our SSRs.

Can’t speak for 100G or 40G cards. No experience in that


From SSR documentation:
Most BRAS features (PPPoE, CLIPS, L2TP LAC, L2TP LNS) are available on 8801 starting with IPOS Rel 16B.
But not all! For example I would miss L2TP Tunnel Switch.

If you have access to SSR documentation you can check the available features in the Document “SSR and Router 8801 Card feature Matrix”.
As we’ve learned it is very important to know, which card is supporting which features. So this document is always laying on my desk to have a fast access in the case we configure something and it doesn’t work.

The biggest pain in those things is, that IPOS allows you to configure all features WITHOUT any warning or error message. But if the card doesn’t support it, it will simply NOT work.

Hi guys,

I have to choose new BGN gears to replace my old SE600s as LNS, and I'm quite interested to check at various points of view ; what made you choose the SSR (apart the copy/paste of old config) ?

We'll investigate ASR1k / 7750 / MX / SSR...

The question is to Thomas, but I'll write my point of view.
Most of our subscribers use CLIPS. This is patent owned by Ericsson. It
is great, working perfectly, but I'am not sure about others implementing
this
the same way as ericsson does.

There is something called FSOL (First Sign of Life) on Cisco (ASR1001x,
ASR9001), however it is bit different than CLIPS, I mean - IP Pool is
bound to particular vlan, so IP utilization is not most optimal.
I was told that there is some workaround for this, but this might be a
bit difficult to migrate.

If there is a hardware config for SSR that would have same functions as
SE600 SEOS 12.1.1.12, that would be perfect replacemtn.
However, as traffic grows, ports with 40G/100G capacity are welcome.
SSR8801 already has 100G, but it is not QSFP, so I'am not sure if they
can work in 40G mode (we alredy have 40G ports, but not 100G ports in
switching core).

And licensing, ericsson does licensing per port and per function. So it
will be more expansive than previous series..

There is lot of questions to be asked still..

If you use a unnumbered interface it is possible to keep one pool to all
vlans.

Stanislav, could you please drop here an example of configuration for
such case ?
How is radius working with ASR, is it similar as in SmartEdge ?

Did you try migration from SE to ASR ?

Marcin

We tested A9K and it fully suited our needs, but decided to didn't move
from /// to Cisco. Radius is a bit differ.

I can send you full config and radius logs from our testing stand if you

Also A9K has a cool feature named Geo-Redundancy. It is a L3-based
stateful redundancy mechanism. (On SmartEdge there is no statefull
redundancy at all)

We tested 4 scenarios:

- dual stack pppoe

- dual stack dhcp-subscribers (clips-like)

- ipv4 unclassified ip (like non-dhcp clips l2)

- l3 connected subscribers (like non-dhcp clips l3)

From our point of view there were the following reasons:


- copy/paste of old config (mostly) =;-)

- mostly the same GUI -> no new knowledge necessary

- direct contact to the manufacturer for fast debugging

But we use the SSRs for more than only BNG functions. So our scope maybe something wider than yours.
